Class for software reliability model with s-metrics

Description

Class for software reliability model with s-metrics

Format

R6Class object.

Value

Object of R6Class with methods for software reliability model with s-metrics.

Fields

srms

A list for srms.

coef

A numeric vector for the regression coefficients.

faults

A numeric vector of the number of total faults.

df

An integer for the degrees of freedom of the model (total).

data

Data to esimate parameters.

Methods

print()

This method prints model parameters.

omega()

This method returns a vector of the number of total faults.

coefficients()

This method returns a vector of the coefficients for s-metrics.

init_params(data)

This method changes the model parameters based on a given data. This is used to set the initial value for the fitting algorithm.

set_params(params)

This method sets the model parameters.

set_data(data)

This method sets data.

em(params, data)

This method returns a list with an updated parameter vector (param), absolute difference of parameter vector (pdiff), log-likelihood function for a given parameter vector (llf), the number of total faults (total) via EM algorithm for a given data.

llf(data)

This method returns the log-likelihood function for a given data.
