...question has been asked twice in the past but to my knowldege, it still hasn't been solved. I am doing a zero inflated binomial model using the VGAM package, I need to obtain p values for my Tvalues in the vglm output. code is as follows > mod2=vglm(dmat~Season+Diel+Tidal.phase+Tidal.cycle,zibinomial, data=mp1) > summary(mod2) Call: vglm(formula = dmat ~ Season + Diel + Tidal.phase + Tidal.cycle, family = zibinomial, data = mp1) Pearson Residuals: Min 1Q Median 3Q Max logit(phi) -3.6496 0.273679 0.285619 0.296763 1.0974 logit(mu) -6.3631 -0.0...

I'm trying to use the inflated binomial distribution of zeros (since 75% of the values are zeros) in a randomized block experiment with four quantitative treatments (0, 0.5, 1, 1.5), but I'm finding it difficult, since the examples available in VGAM packages like for example, leave us unsure of how it should be the data.frame for such analysis. Unfortunately the function glm does not have

Lo Lo All of the factors (Whole plot and subplot) are fixed In addition there are a lot of plants that are not affected at all, so there are lot zeros I'm trying to use the vglm function in VGAM package with zibinomial distribution. I'm a little confused about how to input the covariates to indicate a split plot design. My first try was bmod<-vglm(cbind(Infect, Total)~Water*Fert+Slope/(Water*Fert), zibinomial, data=FertPlots) I would like to know if the syntax I have used in the predictors is right fo...
