Added degrees of freedom and p-values to mml results
mml should be faster now
Added drawPV functions that draw plausible values from a normal approximation to the posterior distribution. See the drawPVs function help for details.
the object returned by mml now includes an object itemScorePoints that shows, for each item, the expected and actually occupied score points.
If items have invalid score points an error now shows the itemScorePoints table.
The mml function used to use the bobyqa optimizer and now uses a combination of the optim function and then a Newton's method optimizer
The mml function Taylor series covariance calculation for composite results has been updated so that the correlation is calculated for all subscales simultaneously. This results in covariance matrix that is always positive definite. The old method can be used by requesting "Partial Taylor".
