Subject: Don´t know what test i have to use
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) ?
Thnks very much
