(Internal) Determine if shadowtest assembly was feasible for exposure control purposes

Description

assemblyInFinalThetaSegmentWasFeasibleAtLeastOnceInInterimThetaSegments is an internal function for determining if shadowtest assembly was feasible for exposure control purposes. Specifically, for the segment k the final theta estimate belonged to, it returns TRUE if shadowtest assembly was feasible at any interim theta that also belonged to k, and returns FALSE otherwise.

Usage

assemblyInFinalThetaSegmentWasFeasibleAtLeastOnceInInterimThetaSegments(
  x,
  final_theta_segment
)

Arguments

x	an output_Shadow object, containing data for a single examinee.
final_theta_segment	the segment the final theta estimate belonged to.

Details

Example 1:

• Interim theta segments are 1, 2, 3, 4, 5, 1, 2, 3, 4, 5

• Shadowtest feasibility are 1, 1, 1, 0, 0, 1, 0, 0, 0, 0

• Final theta estimate is in segment 3

• From the two vectors, segments where shadowtest assembly was feasible: 1, 2, 3, 1

• Final theta segment 3 is an element of the above vector. Return TRUE

Example 2:

• Interim theta segments are 1, 2, 3, 4, 5, 1, 2, 3, 4, 5

• Shadowtest feasibility are 1, 1, 1, 0, 0, 1, 0, 0, 0, 0

• Final theta estimate is in segment 4

• From the two vectors, segments where shadowtest assembly was feasible: 1, 2, 3, 1

• Final theta segment 4 is not an element of the above vector. Return FALSE

Value

assemblyInFinalThetaSegmentWasFeasibleAtLeastOnceInInterimThetaSegments returns TRUE or FALSE.
