This function performs back-transformation from re-parameterized forms in the 'VFP'-package into the original form.
bt.coef(object, K = NULL, signJ = NULL, model = NULL, ...)(object) of class 'gnm' representing a fitted model in re-parameterized form
(numeric) constant value 'K'
(integer) either 1 or -1
(integer) specifying which model shall be back-transformed
additional parameters
(numeric) vector of coefficients in original parameterized form
In the 'VFP' package models are re-parameterized to have better control over the constraint solution-space, i.e. only models may be fitted generating non-negative fitted values. This function is intended to be for internal use only.
