Hello, I?m starting with my PhD and I have to stop because i got a little knowledge in R and statistics. I?ve got a model of this kind: binary response variable: prevalence of infection (0/1) 3 categorical independent variables: sex, month and name of the area I was trying with a full model like this, before the simplification model<-aov(prevalencia~sex*month*area) but the Fligner test told that i haven?t got homoscedascity, so I suppose I should trying with glm, with a model model2<-glm(prevalencia~edad*sexo*mes*zona,binomial) is that correct? where I must put the link (logit) ?
Why not read the help page regarding binomial that is on the help page for glm. There you will learn what the default link is for binomial.
