In tobiasmuetze/gscounts: Group Sequential Designs with Negative Binomial Outcomes

Information level for log rate ratio

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
get_info_gsnb(rate1 = 0.1,
              rate2 = 0.125,
              dispersion = 4, 
              followup1 = seq(1, 3, length.out = 10), 
              followup2 = seq(1, 3, length.out = 10))
