eval_functions: Evaluate basis functions

In andreaskapou/BPRMeth: Model higher-order methylation profiles

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.
