negative predicted values in poisson glm
Dear R helpers,
running the following code of a glm model of the family poisson, gives
predicted values < 0. Why?
library(MASS)
library(stats)
library(mvtnorm)
library(pscl)
data(bioChemists)
poisson_glm <- glm(art ~ fem + mar + kid5 + phd + ment, data = bioChemists,
family = poisson)
predicted.values = predict(poisson_glm)
range(predicted.values)
Thank you in advance for any hints.
Best regards,
P. Olsson

Using at.level() with a MCMCglmm zero-inflated poisson model
...on examples that use the
at.level(trait, x):variableName syntax.
Specifically, the MCMCglmm course notes, available on the package's CRAN
page, uses the following example on page 102:
m5d.1 <- MCMCglmm(art ~ trait - 1 + at.level(trait, 1):fem +
at.level(trait, 1):mar + at.level(trait, 1):kid5 + at.level(trait, 1):phd
+ at.level(trait, 1):ment, rcov = ~idh(trait):units,
data = bioChemists, prior = prior.m5d.1, family = "zipoisson",
verbose = FALSE)
I have been unable to find an answer to the following questions and would
appreciate any guidance:
1) Does at.level(trait, 1) i...
