...or jml bias is provided for as an optional argument in the
function. Currently, the package includes the following:
1) jml() a function for joint maximum likelihood estimation of the Rasch
model
2) alpha() , coefficient alpha
3) alpha.Summary(), gives what alpha would be if item i were excluded
3) scoreCon(), create score conversion tables,
4) class.acc(), classification accuracy statistics
5) simRasch(), simulate Rasch item responses
6) classical(), point-biserial and p-values
Future versions will include Master's partial credit model, DIF
statistics, procedures for linking scales (e.g., St...
