pamm {pammtools} | R Documentation |
A thin wrapper around gam
, however, some arguments are
prespecified:
family=poisson()
and offset=data$offset
.
These two can not be overwritten. In many cases it will also be advisable to
set method="REML"
.
pamm(formula, data = list(), ..., trafo_args = NULL, engine = "gam") is.pamm(x) ## S3 method for class 'pamm' print(x, ...) ## S3 method for class 'pamm' summary(object, ...) ## S3 method for class 'pamm' plot(x, ...)
