Hi there! Happy new year to everyone!
There's a piece of code that I must write that's driving me crazy.
Maybe any of you has previous experiences in something similar. Any help
will be greatly appreciated!
The problem is as follows. I have a matrix Z with dimensions c(m,
p). I have two vectors
Gamma and Th with length p.
What I want to do is, for j in 1:p, for each pair (Gamma[j], Th[j]),
apply the logistic function to each column of z, using plogis(Z[,j],
Th[j], 1/Gamma[j]). Then, by concatenating the result of each iteration
I would obtain a matrix lZ with dimensions c(m, p).
Now, the question is: is there a neat way to do this in a single
step, i.e., without the obvious loop? I have a not-so-good relationship
with the "apply" family, but I suspect there should be a way. Sorry if
this is a silly question...
Thanks and best wishes for the new year to you all! Salud!
