Hello,I am trying to perform a logistic regression using counts. For example: cedegren<- read.table("http://www.cloudstat.org/index.php?do=/attachment/download/id_95 /", header=T) attach(cedegren) ced.del<- cbind(sDel, sNoDel) ced.logr<- glm(ced.del ~ cat + follows + factor(class), family=binomial("logit")) This works. However, if I change the family to Gaussian: ced.logr<- glm(ced.del ~ cat + follows + factor(class), family=gaussian) I get the error: Error: (subscript) logical subscript too long I would like to use the probit function. Is this possible?
I think that you don't understand the 'family=' argument in glm (nor, perhaps, generalized linear models as such). Hint: check ?family. Peter Ehlers
