Description

Calculates the information level for the log rate ratio of the negative binomial model

Usage

get_info_gsnb(rate1, rate2, dispersion, followup1, followup2)

Arguments

rate1

numeric; rate in treatment group 1

rate2

numeric; rate in treatment group 2

dispersion

numeric; dispersion (shape) parameter of negative binomial distribution

followup1

numeric vector; individual follow-up times in treatment group 1

followup2

numeric vector; individual follow-up times in treatment group 2

Value

numeric; information level

Examples

# Calculates information level for case of 10 subjects per group
# Follow-up times of subjects in each group range from 1 to 3
