Description
This function is generic; method functions can be written to handle specific classes of objects.
Usage
logLik1(modfit, dt1, dtInit)
Arguments
modfit |
an object representing model fitted to data using ML estimation. |

a data frame with data for one subject, for whom the log-likelihood function is to be evaluated |
dtInit |
an optional auxiliary data frame. |

subject to the overall log-likelihood returned by
logLik()
function.
