Re: [R] New variables "remember" how they were created?

ental variable (the result of fitting y against all of the instruments). So how does R know that yd should be replace by (z - y.1) unless yd carries some information that it was originally created as (y - y.1). Maybe this question is best asked on the devel list? Cheers, Skipper > Reg

[R] New variables "remember" how they were created?

Hello all, I hope this question is appropriate for this ML. Basically, I am wondering if when you create a new variable, if the variable holds some information about how it was created. Let me explain, I have the following code to replicate an example in a textbook (Greene's Econometric Analysis

[R] What is the Datasets License?

Hello, I saw that this question has been asked here before but couldn't find an answer. Are the raw datasets in R in the public domain? Most are based on quite old "classic" published results, so I would then assume that the raw data is public domain rather than GPL. Can anyone answer this defi

[R] GLM Gamma Family logLik formula?

Hello all, I was wondering if someone can enlighten me as to the difference between the logLik in R vis-a-vis Stata for a GLM model with the gamma family. Stata calculates the loglikelihood of the model as (in R notation) some equivalent function of -1/scale * sum(Y/mu+log(mu)+(scale-1)*log(Y)+l
