Specification of conditional transformation models
ctm(response, interacting = NULL, shifting = NULL, data = NULL,
todistr = c("Normal", "Logistic", "MinExtrVal"),
sumconstr = inherits(interacting, c("formula", "formula_basis")), ...)
a basis function, ie, an object of class basis
a basis function, ie, an object of class basis
a basis function, ie, an object of class basis
either a data.frame
containing the model variables
or a formal description of these variables in an object of class vars
a character vector describing the distribution to be transformed
a logical indicating if sum constraints shall be applied
arguments to as.basis
when shifting
is a formula
An object of class ctm
.
This function only specifies the model which can then be fitted using
mlt
. The shift term is positive by default.
