Fitting GLMM models with glmer
...es came from a paper by Nelson et al. (Use of the
Probability Integral Transformation to Fit Nonlinear Mixed-Models
with Nonnormal Random Effects - 2006). Firstly the authors fit a
Poisson model with canonical link and a single normal random effect
bi ~ N(0;Sigma^2).The SAS routine was:
log_s =log(SURVT)
cens=1
proc nlmixed data=liver;
parms logsig2 = 0 b0 = -2.8 btrt = -0.54 bhrt =0.18;
xb= log_s + b0 + btrt * treat + bhrt * heart+ bi;
lambda=exp(xb);
model cens ~ poisson(lambda);
random bi ~ normal(0,exp(logsig2)) subject=INST;
run;
I obtained the same results for parameters estimates and
stand...

Help
Hello,
I have a question and need your help urgently. I am new to R but want to learn it.
I have several files in a folder which I have imported to R using :
temp = list.files(pattern="*.txt")
>myfiles = lapply(temp, read.delim)
The resulting files are on the workspace stored as List[110]. So they are 110 files in the list. Each file has several different columns and rows.
My
