I am trying to analyse binomial winner/loser data i.e. zeros and ones, I've used the following script:
ft.Model = glmer(winner ~ pairing + complex + pairing:complex + (1|pairID), family = "binomial", data = intra)
anova(ft.Model, test = "Chisq")
However, when I run this the following warning message appears:
In anova.merMod(ft.Model, test = "Chisq") :
additional arguments ignored: ‘test’
but it does also give results that look like this:
Analysis of Variance Table
npar Sum Sq Mean Sq F value
pairing 1 0.47827 0.47827 0.4783
complex 1 0.57937 0.57937 0.5794
pairing:complex 1 0.00000 0.00000 0.0000
so all zeros for the interaction term, which is really strange.
Can anyone tell me the reason for the error message and why this might be happening and an alternative solution. Thanks in advance.
