Dear all,

I am conducting a meta-analysis on a binomial variable. I used the
following code

*> pes.glmm=rma.glmm(xi=nlameanimal, ni=ssizeanimal,
data=prevalence_2020_nomv, measure="PLO")*

*> pes=predict(pes.glmm, transf=transf.ilogit)> print(pes)*

A got the following warning:

*Registered S3 methods overwritten by 'lme4' :*

*  method                          from   cooks.distance.influence.merMod
car    influence.merMod                car    predict.merMod
   MuMIn  dfbeta.influence.merMod         car    dfbetas.influence.merMod
     car *

I did get an output for the analysis but would like to confirm that this is
just a warning and has not had any implication on the analysis and
consequently the output. Many thanks for any help.

Wishing all a great afternoon,
