Examinees

Struct

Psychometrics.Examinee — Type

Examinee <: AbstractExaminee

Description

An immutable containing the information about the examinee (the test taker).

Fields

idx::Int64: An integer that identifies the Examinee in this session.
id::String: A string that identifies the Examinee.
latent::Latent: A mutable latent struct associated with the Examinee.

Factories

Examinee(idx::Int64, id::String, latent::AbstractLatent) = new(idx, id, latent)
Examinee(idx::Int64, latent::AbstractLatent) = new(idx, string(idx), latent)

Creates a new Examinee with custom index, (id) and a latent variable.

Random default initializers (1-D latent)

Examinee(idx::Int64) = new(idx, string(idx), Latent1D())
Examinee(idx::Int64, id::String) = new(idx, id, Latent1D())

Description

Randomly generates an Examinee with custom index and id and with a default 1-dimensional latent variable (Look at (Latent1D)[#Psychometrics.Latent1D] for the defaults).
