An S4 class to represent CAT simulation results.

`numExaminees`

a positive integer representing the number of simulated examinees.

`trueThetas`

a numeric vector representing the true theta values of simulated examinees.

`finalThetas`

a numeric vector representing the final theta estimates of simulated examinees.

`finalThetaSEs`

a numeric vector representing the final theta estimate standard errors (SEs) of simulated examinees.

`estThetas`

a list of length

`numExaminees`

. Each element of the list is a numeric vector representing theta estimate at adaptive stages for the simulated examinee.`estThetaSEs`

a list of length

`numExaminees`

. Each element of the list is a numeric vector representing theta estimate standard error (SE) at adaptive stages for the simulated examinee.`scores`

a list of length

`numExaminees`

. Each element of the list is a numeric vector representing scores at adaptive stages for the simulated examinee. 0 for an incorrect repsonse and 1 for a correct respone.`itemsAdministered`

a list of length

`numExaminees`

. Each element of the list is a character vector representing identifiers of adminsitered items at adaptive stages for the simulated examinee.`shadowTests`

a list of length

`numExaminees`

. Each element of the list is also a list representing the shadow test assembled at each adaptive stage.`engineTime`

a list of length

`numExaminees`

. Each element of the list is a numeric vector representing the engine time at each adaptive step. the engine time includes time consumed by CAT algorithms and shadow test assembly.
