### Description

Cat object containing item parameters for graded response model fit with responses to the 16 item Need to Evaluate inventory

### Usage

data(nte_cat)


### Format

An object of class Cat of length 1.

### Details

Cat object containing item parameters for graded response model fit with 2534 response profiles from MTurk, 4993 response profiles collected by Qualtrics in June 2018, and 1512 response profiles from The American Panel Survey (TAPS) in December 2014. TAPS is a monthly online panel survey of about 2,000 adults in the United States. The panel was recruited in the fall of 2011 using an address-based sampling frame. TAPS surveys are administered online. Selected panelists who do not have a computer or online service are provided a computer and internet access by TAPS.

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 TAPS sample (.002) 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:

5 = Extremely characteristic of me, 4 = Somewhat characteristic of me, 3 = Uncertain, 2 = Somewhat uncharacteristic of me, 1 = Extremely uncharacteristic of me
