relBackgroundLL {EffectsRelBaseline} | R Documentation |
Compute the log-likelihood ratio of the grouped responses being obtained from a background distribution given its mean and variance.
relBackgroundLL(resp, groups, backMean, backVar)
resp |
response values |
groups |
grouping variables (will be treated as factors) |
backMean |
mean of the background distribution |
backVar |
variance of the background distribution |
log-likelihood ratio
This is the log-likelihood ratio of the changes from background test (CBT). It is included here for comparison.
