UPDATED POST- Some Models I use for Business Strategy- to analyze the huge reams of qualitative and uncertain data that business generates.
- Porters 5 forces Model-To analyze industries
- BCG Matrix- To analyze Product Portfolios
- Porters Diamond Model- To analyze locations
- McKinsey 7 S Model-To analyze teams
- Gernier Theory- To analyze growth of organization
- Herzberg Hygiene Theory- To analyze soft aspects of individuals
- Marketing Mix Model- To analyze marketing mix.
I really liked the initiatives at JMP/Academic. Not only they offer the software bundled with a textbook, which is both good common sense as well as business sense given how fast students can get confused
(Rant 1 Bundling with textbooks is something I think is Revolution Analytics should think of doing instead of just offering the academic version for free downloading- it would be interesting to see the penetration of R academic market with Revolution’s version and the open source version with the existing strategy)
Major publishers of introductory statistics textbooks offer a 12-month license to JMP Student Edition, a streamlined version of JMP, with their textbooks.
and a glance through this http://www.jmp.com/academic/pdf/jmp_se_comparison.pdf shows it is a credible and not extremely whittled down version which would be just dishonest.
And I loved this Reference Card at http://www.jmp.com/academic/pdf/jmp10_se_quick_guide.pdf
Oracle, SAP- Hana, Revolution Analytics and even SAS/STAT itself can make more reference cards like this- elegant solutions for students and new learners!
More- creative-rants Honestly why do corporate sites use PDFs anymore when they can use Instapaper , or any of these SlideShare/Scribd formats to show information in a better way without diverting the user from the main webpage.
But I digress, back to JMP

The Necessity of Cyber War as a better alternative to traditional warfare
By the time our generation is done with this living on this planet, we should have found a way to flip warfare into just another computer game.
- Cyber War does not kill people but does diminish both production as well offensive capabilities of enemy.
- It destroys lesser resources of the enemy irreversibly, thus leading to increased capacity to claim damages or taxes from the loser of the conflict
- It does not motivate general population for war hysteria thus minimizing inflationary pressures
- Cyber War does not divert too many goods and services (like commodities, metals, fuels) from your economy unlike traditional warfare
- Capacity to wage cyber war needs human resources and can reduce asymmetry between nations in terms of resources available naturally or historically (like money , access to fuel and logistics, geography , educated population,colonial history )
- It is more effective in both offensive and defensive capabilities and at a much much cheaper cost to defense budgets
- Most developed countries have already invested heavily in it, and it can render traditional weaponry ineffective and expensive. If you ignore investing in cyber war capabilities your defense forces would be compromised and national infrastructure can be held to ransom
Self-defence….is the only honourable course where there is unreadiness for self-immolation.- Gandhi.
Ajay- Why did you choose Rapid Miner and R? What were the other software alternatives you considered and discarded?
Analyst- We considered most of the other major players in statistics/data mining or enterprise BI. However, we found that the value proposition for an open source solution was too compelling to justify the premium pricing that the commercial solutions would have required. The widespread adoption of R and the variety of packages and algorithms available for it, made it an easy choice. We liked RapidMiner as a way to design structured, repeatable processes, and the ability to optimize learner parameters in a systematic way. It also handled large data sets better than R on 32-bit Windows did. The GUI, particularly when 5.0 was released, made it more usable than R for analysts who weren’t experienced programmers.
Ajay- What analytics do you do think Rapid Miner and R are best suited for?
Analyst- We use RM+R mainly for sports analysis so far, rather than for more traditional business applications. It has been quite suitable for that, and I can easily see how it would be used for other types of applications.
Ajay- Any experiences as an enterprise customer? How was the installation process? How good is the enterprise level support?
Analyst- Rapid-I has been one of the most responsive tech companies I’ve dealt with, either in my current role or with previous employers. They are small enough to be able to respond quickly to requests, and in more than one case, have fixed a problem, or added a small feature we needed within a matter of days. In other cases, we have contracted with them to add larger pieces of specific functionality we needed at reasonable consulting rates. Those features are added to the mainline product, and become fully supported through regular channels. The longer consulting projects have typically had a turnaround of just a few weeks.
Ajay- What challenges if any did you face in executing a pure open source analytics bundle ?
Analyst- As Rapid-I is a smaller company based in Europe, the availability of training and consulting in the USA isn’t as extensive as for the major enterprise software players, and the time zone differences sometimes slow down the communications cycle. There were times where we were the first customer to attempt a specific integration point in our technical environment, and with no prior experiences to fall back on, we had to work with Rapid-I to figure out how to do it. Compared to the what traditional software vendors provide, both R and RM tend to have sparse, terse, occasionally incomplete documentation. The situation is getting better, but still lags behind what the traditional enterprise software vendors provide.
Ajay- What are the things you can do in R ,and what are the things you prefer to do in Rapid Miner (comparison for technical synergies)
Analyst- Our experience has been that RM is superior to R at writing and maintaining structured processes, better at handling larger amounts of data, and more flexible at fine-tuning model parameters automatically. The biggest limitation we’ve had with RM compared to R is that R has a larger library of user-contributed packages for additional data mining algorithms. Sometimes we opted to use R because RM hadn’t yet implemented a specific algorithm. The introduction the R extension has allowed us to combine the strengths of both tools in a very logical and productive way.
In particular, extending RapidMiner with R helped address RM’s weakness in the breadth of algorithms, because it brings the entire R ecosystem into RM (similar to how Rapid-I implemented much of the Weka library early on in RM’s development). Further, because the R user community releases packages that implement new techniques faster than the enterprise vendors can, this helps turn a potential weakness into a potential strength. However, R packages tend to be of varying quality, and are more prone to go stale due to lack of support/bug fixes. This depends heavily on the package’s maintainer and its prevalence of use in the R community. So when RapidMiner has a learner with a native implementation, it’s usually better to use it than the R equivalent.
I have been busy-
1) Finally my divorce came through. My advice – dont do it without a pre-nup ! Alimony means all the money.
2) Spending time on Quora after getting bored from LinkedIn, Twitter,Facebook,Google Plus,Tumblr, WordPress
See this answer to-
1) we will change the world
2) if we get 1% of a billion people market, we will be rich
3) if we have got funding, most of the job is done
4) lets pay ourselves high salaries since we got funded
5) our idea is awesome and cant be copied, improvised, stolen, replicated
6) startups are painless
7) it is a better life than a corporate career
8) long term vision is important than short term cash burn
9) we will never sell out or exit. never
10) its a great idea to make startups with friend
Say hello to me – http://www.quora.com/Ajay-Ohri/answers
3) Writing freelance articles on APIs for Programmable Web
Why write pro? See point 1)
4) Writing poetry on http://poemsforkush.com/. It now gets 23000 views a month. I wish I could say my poems were great, but the readers are kind (364 subscribers!) and also Google Image Search is very very kind.
5) Kicking tires with next book ” R for Cloud Computing” and be tuned for another writing announcement
6) Waiting for Paul Kent, VP, SAS Big Data to reply to my emails for interview after HE promised me!! You dont get to 105 interviews without being a bit stubborn!
7) Sighing on politics engulfing my American friends especially with regards to Chic-fil-A and Romney’s gaffes. Now thats what I call a first world problem! Protesting by eating or boycotting chicken sandwiches! In India we had the world’s biggest blackout two days in a row- and no one is attending the Hunger Fast against corruption protests!
8) Watching Olympics! Our glorious nation of 1.2 billion very smart people has managed to win 1 Bronze till today!! Michael Phelps has won more medals and more gold than the whole of India has since the Olympics Games began!!
9) Consulting to pay the bills. includes writing R code, making presentations. Why consult when I have writing to do? See point 1)
10) Reading New York Times to get insights on Big Data and Analytics. Trust them- they know what they are doing!
- Servers were okay, it was the DNS server that got swamped.
- I am sorry for the downtime- hopefully you didnt even notice
- I have faced challenges like domain name hijacking, sql injection , malicious WP plugins and thats why shifted to a professional hosting. I stand by my vendors and their professional judgement, moving away would mean the hackers won.
- This was very clever to swamp the DNS provider- my compliments to the tech talent behind this.
- You would think that every webmaster would have a back up plan in case his site went dDOS, but surprisingly even corporate websites dont have a back up (under attack) plan
