Fit a boosting conditional logit model using componentwise smoothing spline.
1 | clogitboost(y, x, strata, iter, rho)
|
y |
vector of binary outcomes. |
x |
matrix or data frame with each column being a covariate. |
strata |
vector of group membership, i.e., items in the same group have the same value. |
iter |
number of iterations. |
rho |
learning rate parameter in the boosting algorithm. |
The function clogitboost
returns the following list of values:
call |
original function call. |
func |
list of fitted spline functions. |
index |
list of indices indicating which covariate is used as input for the smoothing spline. |
theta |
list of fitted coefficients in the conditional logit models. |
loglike |
sequence of fitted values of log-likelihood. |
infscore |
relative influence score for each covariate. |
rho |
learning rate parameter, which typically takes a value of 0.05 or 0.1. |
xmax |
maximal element of each covariate. |
xmin |
minimal element of each covariate. |
