Description
Formula parsing and model matrix computations for gradient boosting functions.Usage
boost_dpp(formula, data, weights = NULL, na.action = na.omit, ...)
Arguments
formula
a symbolic description of the model to be fit.
data
a data frame containing the variables in the model.
weights
an optional vector of weights to be used in the fitting
process.
na.action
a function which indicates what should happen when the data
contain NAs.
...
additional arguments passed to callies.
Value
- An object of class
boost_data.
Details
Some very basic formula parsing and model matrix computations.
