(Internal) Parse eligibility flags for a specific theta segment

Description

getEligibilityFlagInSegment is an internal function for obtaining item/set-level eligibility flags for a specific theta segment.

Usage

getEligibilityFlagInSegment(eligiblity_flag, segment, simulation_constants)

Arguments

eligiblity_flag	a list containing segment-wise eligibility flags.
segment	the segment index to read from.
simulation_constants	a named list containing simulation constants.

Value

getEligibilityFlagInSegment returns a named list containing the following:

i

a length-ni) vector of 1 and 0 values.

s

a length-ns) vector of 1 and 0 values. Only returned when simulation_constants$group_by_stimulus is TRUE.

In each vector, 1 indicates the item/set is eligible to be selected in a shadowtest, and 0 indicates the item/set is not eligible to be selected in a shadowtest. The higher the observed exposure rate, the more likely the item/set will be flagged as 0.
