mnnegLL {MQMF} | R Documentation |
mnnegLL generic multinomial negative log-likelihoods
Description
mnnegLL a generic multinomial negative log-likelihood that requires observed frequencies and predicted frequencies, although the predicted frequencies could also be the final proportions, as long as they sum to one. It checks that the number of predicted values matches the number of observed values
Usage
mnnegLL(obs, predf)
Arguments
obs |
the original observed frequencies |
predf |
the predicted frequencies or proportions |
Value
a single scalar value
Examples
obs <- c(0,0,6,12,35,40,29,23,13,7,10,14,11,16,11,11,9,8,5,2,0)
predf <- c(0.1,0.9,4.5,14.4,29.7,39.9,35.2,21.3,10.9,8.0,9.5,12.1,
14.1,14.7,13.7,11.5,8.6,5.8,3.5,1.9,0.9)
mnnegLL(obs,predf) # should be 705.5333
