predict
methods for the clogitboost
objects, which produce marginal predictions of the covariate effects.
## S3 method for class 'clogitboost'
predict(object, x, strata, ...)
object |
output object from the |
x |
new matrix or data frame with each column being a covariate. |
strata |
new vector of group memberships, i.e., items in the same group have the same value. |
... |
not currently used. |
The method predict
returns the following list of values:
prob |
