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.
