Hello, I'm working on a Cox Proportional Hazards model for a cancer data set that has missing values for the categorical variable "Grade" in less than 10% of the observations. I'm not a statistician, but based on my readings of Frank Harrell's book it seems to be a candidate for using multiple imputation technique(s). I understand the concepts behind imputation, but using

Hello all, I am a medical student and as a capstone for my summer research project I am going to create a simple online web "calculator" for users to input their relevant data, and a probability of relapse within 5 years will be computed and returned based on the Cox PH model I have developed. The issue I'm having is finding a definitive method/function to feed the user's

Hello, Here is the data set I am working with: dat=read.csv('http://dl.dropbox.com/u/1852742/relexpressions.csv') names(dat) #Under the 'target' column, I want to change all of the values into all capital letters (e.g. fgf2 becomes FGF2). I have taken a loop approach but I think my Python background is confusing me. Here is what I attempted: for(line in
