incrementAlpha function

(Internal) Increment exposure record variable: alpha

incrementAlpha is an internal function for incrementing an exposure record variable. Specifically, the a_ijk is incremented by one for administered items/sets.

incrementAlpha(
  exposure_record,
  segments_to_apply,
  segment_prob,
  x,
  simulation_constants
)

Arguments

• exposure_record: a named list containing exposure records.
• segments_to_apply: which segments to apply the incrementing.
• segment_prob: the amount of increment.
• x: an output_Shadow object, containing data for a single examinee.
• simulation_constants: a named list containing simulation constants.

Returns

incrementAlpha returns an updated exposure record.
