`R6Class`

object.

Object of `R6Class`

with methods for software reliability model with s-metrics.

`srms`

A list for srms.

`params`

A numeric vector for the regression coefficients.

`df`

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

`data`

Data to esimate parameters.

`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.
