object |
an object of class |
type |
type of residuals to be displayed.
Can be either |
df.p |
logical; print the degrees of freedom and p-values? |
full.scores |
logical; compute relevant statistics for each subject in the original data? |
QMC |
logical; use quasi-Monte Carlo integration? If |
printvalue |
a numeric value to be specified when using the |
tables |
logical; for LD type, return the observed, expected, and standardized residual tables for each item combination? |
verbose |
logical; allow information to be printed to the console? |
Theta |
a matrix of factor scores used for statistics that require empirical estimates (i.e., Q3).
If supplied, arguments typically passed to |
suppress |
a numeric value indicating which parameter local dependency combinations to flag as being too high. Absolute values for the standardized estimates greater than this value will be returned, while all values less than this value will be set to NA |
theta_lim |
range for the integration grid |
quadpts |
number of quadrature nodes to use. The default is extracted from model (if available) or generated automatically if not available |
