Regression modeler {MXM}

Generic regression modelling function

Description

Generic regression modelling function.

Usage

modeler(target, dataset = NULL, test = "testIndFisher")

Arguments

target

The target (dependent) variable. It can be a numerical variable, factor, ordinal factor, percentages, or time to event.

dataset

The predictor variable(s). It can be a vector, a matrix with continuous only variables. If there are no predictor variables leave this NULL.

test

Unlike reg.fit this accepts the test. The test argument is exactly like in all feature selection methods. This function accepts the following: "testIndReg", "testIndPois", "testIndNB", "testIndLogistic", "testIndMMReg", "testIndRQ", "testIndBinom", "censIndCR", "censIndWR", "censIndLLR", "testIndBeta", "testIndGamma, "testIndNormLog", "testIndTobit", "testIndQPois", "testIndQBinom", "testIndFisher", "testIndMultinom" and "testIndOrdinal".

Details

This is a generic regression function designed for continuous predictor variables only. It was useful for me so I decided to epxort it.

Value

A list including:

mod

The fitted model.

dev

The deviance. For some models though ("testIndMMReg", "testIndRQ", "censIndCR", "censIndWR", "testIndTobit", "testIndBeta", "testIndNB", ""testIndQPois", "testIndQBinom") this contains twice the log-likelihood.

bic

The BIC of the model. This is NA for the "testIndQPois" and "testIndQBinom" because they are quasi likhelidood models and hence have no BIC.

res

The residuals of the fitted model.

Examples

#simulate a dataset with continuous data
dataset <- matrix(runif(100 * 5, 1, 100), nrow = 100 ) 
#the target feature is the last column of the dataset as a vector
target <- dataset[, 1]
dataset <- dataset[, -1]
a <- modeler(target, dataset)
