Hello guys, i looked over the archive files and found nothing about this
kind of error.
I have a database of 33 elements described in 8 variables, i'm using the
Leave-One-Out iterative process
to take one of the elements to be the test element and make a regression
with the other 32 and then
I try to predict the clas of the element out.
I'm using this call as a part of a Leave-One-Out experiment:
glmresult <- glm(Y ~ x1+x2+x3+x4+x5+x6+x7+x8, family=binomial,
control=glm.control(epsilon = 1e-8, maxit = 100, trace = FALSE))
but when i look at the coefficients with:
coef(glmresult)
Everything goes well (i get all the coefficients) until the 27th element
which gets a NA as a coefficient to variable x8
The vectors Y, x1,x2,x3,x4,x5,x6,x7,x8 have the same length and there isn't
any missing data.
don't know what to do right now as i already reviewed the code a lot and i'm
starting to think the problem is in the
data.
