t.coef | R Documentation |
This function performs transformation from the original parameterization into the 'VFP'-package internal re-parameterized form.
## S3 method for class 'coef' t( coeffs0, K = NULL, Maxi = NULL, model = NULL, signJ = NULL, eps = sqrt(.Machine$double.eps), ... )
coeffs0 |
(numeric) vector of function coefficients to be transformed into the re-parameterized form |
K |
(numeric) constant value 'K' |
Maxi |
(numeric) max. value |
model |
(integer) specifying which model shall be back-transformed |
signJ |
(integer) either 1 or -1 |
eps |
(numeric) constant used instead of zero in case of log-transformation |
... |
additional parameters |
In the 'VFP' package models are re-parameterized to have better control over the constrained solution-space, i.e. only models may be fitted generating non-negative fitted values. This function is intended to be for internal use only.
(numeric) vector of coefficients in re-parameterized form
