[R] deal with R.package panel

[Pavel Khomski]

hello!

my question conserns with use of "panel" package (written by R.C.Gentlman)
(unfortunately the manual and help sites are very short)

1. is it possible to do analysis  just without a(ny) covariate? i 
suggest do it by introducing a covariate with level=0 in all 
obervations, this because of Q(z)=Q_o exp(beta*z),  but it seemingly 
doesn't work

2. in the option gamma in the call of panel function: do you mean an 
initial value for parameter vector gamma?
say if i have 3 theta-parameters, so i have to initialize 
gamma=c(xxx,xxx,xxx), correct?

3. are the (first ) observed times =0 allowed (in $time vectors) or 
schould in such a case begin with =1, if there are any?


thanks for your response
