grad_ll {iotarelr}

Gradient for Log Likelihood in Condition Stage

Description

Function written in C++ estimating the gradient of the log likelihood function for a given parameter set and given observations.

Usage

grad_ll(param_values, observations)

Arguments

param_values

NumericVector containing the probabilities of a multinominal distribution. The length of this factor is the number of categories - 1 since it contains only the parameters to be estimated.

observations

NumericVector containing the number of observations for each category of the multinominal distribution. The length of this vector equals the number of categories.

Value

Returns the gradient as a NumericVector.
