Description Details Note Author(s) References See Also

Description

The difNLR package containts DIF detection method based on non-linear regression. Both uniform and non-uniform DIF effects can be detected when considering one focal group. DIF detection method is based either on likelihood-ratio test, or on F-test of submodel. Package also offers DDF detection method based on multinomial log-linear regression model.
