This function retrieves the coefficients from a fitted 'colsa' object.
Usage
# S3 method for class 'colsa'
coef(object, ...)
Arguments
- object
An object of class 'colsa'. The fitted model object from which
coefficients are to be extracted.
- ...
Additional arguments (currently not used).
Value
A numeric vector containing the coefficients extracted from the
'colsa' object.
Details
The function verifies that the input object is of class 'colsa'.
It then calculates the coefficients by applying a transformation matrix
(prox) to the theta parameter of the object. The transformation matrix
accounts for the number of basis functions and features in the model.
