Details
Cat object containing item parameters for graded response model fit with 774,410 response profiles by myPersonality Project and 1500 response profiles collected by YouGov in June 2018. The sample from myPersonality Project was a convenience sample, and the respondents from YouGov were matched to a sampling frame on gender, age, race, and education.
See Cat-class for details regarding the Cat object structure.
See grmCat for details regarding the graded response model.
A normal prior was chosen with mean from the theta estimates from the YouGov sample (-.367) and a standard deviation (1.3) wide enough to envelope the range of estimated theta values across both samples.
Note that due to how the item parameters were estimated, large, positive values indicate "more" of the latent trait.
Response options are 1=Very inaccurate; 2=Moderately inaccurate; 3=Neither inaccurate nor accurate; 4=Moderately accurate; 5=Very accurate.
