Hi when I try to run StepAIC algorithm I get the output. But along with the each iteration for AIC calculation.I do get the following warning message. Anyone know what does it mean?
" glm.fit: fitted probabilities numerically 0 or 1 occurredglm.fit: algorithm did not convergeglm.fit: fitted probabilities numerically 0 or 1 occurredglm.fit: algorithm did not convergeglm.fit: fitted probabilities numerically 0 or 1 occurred "
