Description

Compute the log-likelihood ratio of the grouped responses being obtained from a background distribution given its mean and variance.

Usage

1
relBackgroundLL(resp, groups, backMean, backVar)

Arguments

resp

response values

groups

grouping variables (will be treated as factors)

backMean

mean of the background distribution

backVar

variance of the background distribution

Value

log-likelihood ratio

Note

This is the log-likelihood ratio of the changes from background test (CBT). It is included here for comparison.
