Queen the Movie Review (Bollywood 2014)

This is a delicious movie meant to be savored by everyone. It shows how a stood up traditional bride decides to go on her planned honeymoon trip alone. Above all, it shows brown and yellow and white people and black people can have lots of fun together once they shed their stereotypes. Watch it for the lovely colors and nice acting. Great songs and great humor, which you can relate to especially if you are Punjabi /North India.

Go watch and dance with the Queen

R packages for Pharma and Medicine #rstats

There is a dedicated CRAN task view on the various options within the R ecosystem for Clinical Trails

CRAN Task View: Clinical Trial Design, Monitoring, and Analysis http://cran.r-project.org/web/views/ClinicalTrials.html This task view gathers information on specific R packages for design, monitoring and analysis of data from clinical trials. It focuses on including packages for clinical trial design and monitoring in general plus data analysis packages for a specific type of design. Also, it gives a brief introduction to important packages for analyzing clinical trial data . It has the following sub headings.

 

  1. Design and Monitoring
  2. Design and Analysis
  3. Analysis for Specific Designs
  4. Analysis in General
  5. Meta-Analysis

 

 and an additional one on PharmaKinetic Data

CRAN Task View: Analysis of Pharmacokinetic Data http://cran.r-project.org/web/views/Pharmacokinetics.html The primary goal of pharmacokinetic (PK) data analysis is to determine the relationship between the dosing regimen and the body’s exposure to the drug as measured by the nonlinear concentration time curve or related summaries (e.g. the area under the curve). Base R contains nls which can be used to calculate nonlinear least-squares estimates of the parameters from a PK model. It returns an object of the class "nls" having methods coef(),formula()resid()print()summary()AIC()fitted() and vcov(). Four packages are available in CRAN that directly aid in PK data analysis, including; the packages PKPKfitnlmeODE which incorporates nlme and deSolve, and the package PKtools. While PK provides basic pharmacokinetics functions which implement non-compartmental analysis methods, the latter three packages focus on modeling methods.

A relatively new [package] is Greport

http://biostat.mc.vanderbilt.edu/wiki/Main/Greport The greport package contains many functions useful for monitoring and reporting the results of clinical trials and other experiments in which treatments are compared. LaTeX is used to typeset the resulting reports, recommended to be in the context of knitr. The Hmisc and lattice packages are used by greport for high-level graphics.

(NOTE- I wish there was some way to group packages and functions along business domains like finance, telecom, pharma, retail , entertainment) the current system of CRAN views is purely a clustering of packages of similar techniques but not business domains)

What is your Erdos number #rstats

Nice tool here courtesy Microsoft

What is Erdos Number

The Erdős number (Hungarian pronunciation: [ˈɛrdøːʃ]) describes the “collaborative distance” between a person and mathematician Paul Erdős, as measured by authorship of mathematical papers.

The same principle has been proposed for other eminent people in other fields.

New Delhi R User Group goes 200+

The New Delhi R User Group  has now 218 members. We have been meeting regularly since Ocr 2012, and last year we even took Revolution’s generous offer of basic sponsorship with an application this year for a higher level sponsorship.

Meetups are something are new here. We are looking to expand the analytics open source ecosystem here in India- and we welcome any analytics company near NCR area willing to donate office space in Gurgaon , Noida, Delhi once a month to host us.

It is great to see the energy of the next analytics  generation and I feel honored to be surrounded by so many bright and young engineers.

GUIDE- a great GUI for derivatives in #rstats

I was reading a review copy of this fine book ” R for Quantitative Finance” when I came across a GUI for Finance in R – its called the GUIDE package and it’s absolutely is a must for people wanting to try out R based Quant Finance for a risk free trial 😉


I think it can be used to further spread R in the area of teaching finance courses.

See it yourself-

I am too old to do my coding homework #rstats

an email I get from a student when i am teaching R

 

————————————————————–

Hello Ajay,

This is regarding the “XXXXXXXXX” course at EEEE.  Since you mentioned yesterday that submitting the class assignments is mandatory for everyone, I have to express my concern.
I am a senior level BI/DW Architect and executive in the U.S. and approaching the age of 60 years soon close to my retirement).  I have been away from hands on coding for many years now since I always have developers working for/with me who implement the solutions I envision, architect and design (although I have programmed in a variety of platforms for decades before that).  As such, completing programming assignments is not the best use of my time currently due to my professional priorities, business travel and other personal issues including my health, etc.  Hence it is not possible for me to submit the class assignments.  (I chose this class for its timing convenience and remote access form anywhere because I travel a lot and can’t take in-class courses).
My goal in attending this class is to get a good understanding of how R and its statistical tools are used for business analytics.  I know exactly what I need to learn from this class such that I can drive my R / BI developers in the right direction for my intended solutions.  I should mention that I have good college background in Statistics and have used SAS and SPSS before.
As such, I need to have an agreement with you that I will not have to submit the class assignments.  I will sincerely try to solve them mentally to clearly understand the solution but do not have the time to invest in the coding part and struggle with the R syntax.  It would help me (and others) tremendously if you walk through the assignment solutions during each following class.  That would solidify our leanings.
Let me know via reply  if you can give me this exception.  Otherwise, I am willing to drop out of the course and will take that up with the EEE management.
Thanks,
S
