eval_functions {BPRMeth} | R Documentation

## Evaluate basis functions

### Description

Method for evaluating an M basis function model with observation data `obs` and coefficients `w`.

### Usage

    eval_probit_function(obj, ...)

    eval_function(obj, ...)

    ## S3 method for class 'rbf'
    eval_function(obj, obs, w, ...)

    ## S3 method for class 'polynomial'
    eval_function(obj, obs, w, ...)

    ## S3 method for class 'fourier'
    eval_function(obj, obs, w, ...)

### Arguments

`obj` | The basis function object.
`...` | Optional additional parameters
`obs` | Observation data.
`w` | Vector of length M, containing the coefficients of an M^{th}-order basis function.

### Value

The evaluated function values.

NOTE that the `eval_probit_function` computes the probit transformed basis function values.
