With this function data sets according to the Continous Rating Scale Model are simulated
simCRSM(itempar, disp, perspar, mid = 0.5, len = 1, seed = NULL)a numerical vector with item parameters
a number setting the dispersion parameter for the item set
a numerical vector with the person parameters
the midpoint of the response scale (on which the data set is generated)
the length of the response scale (on which the data set is generated)
a seed for the random number generated can optionally be set
simulated data set
the fixed item parameters according to the input
the fixed dispersion parameter according to the input
the fixed person parameters according to the input
The midpoint and the length of the response scale define the interval of the data set generated. The default of the function generates data according to a response scale between 0 and 1 - that is midpoint 0.5 and length 1.
