Hi
 
Does anyone know what this means:
 
 
> glm.model = glm(formula = as.factor(nextDay) ~ ., family=binomial,
data=spi[1:1000,])
> pred <- predict(glm.model, spi[1001:1250,-9], type="response")
Warning message: 
prediction from a rank-deficient fit may be misleading in:
predict.lm(object, newdata, se.fit, scale = 1, type = ifelse(type ==  
 
9 is my determinant and I still get this message even when I remove the
9.
