fit_dk function

Goodness of fit statistics for data with don't know

For data with Don't Know, chi-square goodness of fit between true and model based multivariate distribution

fit_dk(pre_test, pst_test, g, est.param, force9 = FALSE)

Arguments

• pre_test: data.frame carrying pre_test items
• pst_test: data.frame carrying pst_test items
• g: estimates of $\gamma$ produced from guesstimate
• est.param: estimated parameters produced from guesstimate
• force9: Optional. There are cases where DK data doesn't have DK. But we need the entire matrix. By default it is FALSE.

Returns

matrix with two rows: top row carrying chi-square value, and bottom row probability of observing that value
