frac_common_cov: Parameter objects for Regularized Discriminant Models
Description
discrim_regularized() describes the effect of frac_common_cov() and
frac_identity(). smoothness() is an alias for the adjust parameter in
stats::density().
Usage
frac_common_cov(range = c(0, 1), trans = NULL)
frac_identity(range = c(0, 1), trans = NULL)
smoothness(range = c(0.5, 1.5), trans = NULL)
Value
A function with classes "quant_param" and "param"
Arguments
range
A two-element vector holding the defaults for the smallest and
largest possible values, respectively.
trans
A trans object from the scales package, such as
scales::log10_trans() or scales::reciprocal_trans(). If not provided,
the default is used which matches the units used in range. If no
transformation, NULL.
Details
These parameters can modulate a RDA model to go between linear and quadratic
class boundaries.
