makeCalibrationModel function

(internal) construct a model

makeCalibrationModel is an internal function for constructing a model.

makeCalibrationModel(d, dimensions, bound_cov)

Arguments

• d: a PROsetta_data object.
• dimensions: the number of dimensions to use in the model. Must be 1 or 2. If 1, all instruments are modeled to be from one dimension. If 2, each instrument is modeled to be from its own dimension (i.e., calibrated projection is used).
• bound_cov: only used when dimensions is 2. If TRUE, then constrain the between-dimension covariance to be < .999.

Returns

makeCalibrationModel returns a mirt.model object.

Examples

PROsetta:::makeCalibrationModel(data_asq, 1, FALSE)
PROsetta:::makeCalibrationModel(data_asq, 1, TRUE)
PROsetta:::makeCalibrationModel(data_asq, 2, FALSE)
PROsetta:::makeCalibrationModel(data_asq, 2, TRUE)
