Calculate the log-likelihood

Share:

Description

The log-likelihood is calculated with taking into account the type of data ('gaussian', 'binomial', ... etc) and the link function.

Usage

1
  log_lik(y, n, mu, wt, family, nparam, disp_mod)

Arguments

y

Observed values.

n

Vector of '1's and same length as y.

mu

Predicted values.

wt

Weights.

family

An object of class family.

nparam

Number of parameters of the model.

disp_mod

Dispersion of the 'glm' model.

Details

This function calculates the log-likelihood for the exponential family, it uses the 'AIC' function to realise this operatin.

Value

The log-likelihood of an individual (trajectory).

Note

Meant to be used internally.
