In TestDesign: Optimal Test Design Approach to Fixed and Adaptive Test Construction

(Internal) Increment exposure record variable: phi

Description

incrementPhi is an internal function for incrementing an exposure record variable. Specifically, the f_k is incremented by one if the following conditions are simultaneously met:

• For the final theta segment k, shadowtest assembly was feasible at least one times in any item position while interim theta segment was k.

Usage

incrementPhi(
  exposure_record,
  segments_to_apply,
  segment_prob,
  assembly_was_feasible
)

Arguments

exposure_record	a named list containing exposure records.
segments_to_apply	which segments to apply fading to.
segment_prob	a vector containing segment-wise classification probabilities of an ability estimate.
assembly_was_feasible	see assemblyInFinalThetaSegmentWasFeasibleAtLeastOnceInInterimThetaSegments.

Value

incrementPhi returns an updated exposure record.
