output_Shadow_all-class function

Class 'output_Shadow_all': a set of adaptive assembly solutions

output_Shadow_all is an S4 class for representing a set of adaptive assembly solutions. class

Details

• notations: * ni denotes the number of items in the item_pool object. * ns denotes the number of stimuli. * nj denotes the number of participants.

Slots

• call: the function call used for obtaining this object.
• output: a length-nj list of output_Shadow objects, containing the assembly results for each participant.
• final_theta_est: a length-nj vector containing final theta estimates for each participant.
• final_se_est: a length-nj vector standard errors of the final theta estimates for each participant.
• exposure_rate: a matrix containing item-level exposure rates of all items in the pool. Also contains stimulus-level exposure rates if the assembly was set-based.
• usage_matrix: a nj by (ni + ns) matrix representing whether the item/stimulus was administered to each participant. Stimuli representations are appended to the right side of the matrix.
• cumulative_usage_matrix: a nj by (ni + ns) matrix representing the number of times the item/stimulus was administered to each participant over multiple administrations.
• true_segment_count: a length-nj vector containing the how many examinees are now in their segment based on the true theta. This will tend to increase. This can be reproduced with true theta values alone.
• est_segment_count: a length-nj vector containing the how many examinees are now in their segment based on the estimated theta. This will tend to increase. This can be reproduced with estimated theta values alone.
• eligibility_stats: exposure record for diagnostics.
• check_eligibility_stats: detailed segment-wise exposure record for diagnostics. available when config_Shadow@exposure_control$diagnostic_stats is TRUE.
• no_fading_eligibility_stats: detailed segment-wise exposure record without fading for diagnostics. available when config_Shadow@exposure_control$diagnostic_stats is TRUE.
• freq_infeasible: a table representing the number of times the assembly was initially infeasible.
• pool: the item_pool used in the assembly.
• config: the config_Shadow used in the assembly.
• constraints: the constraints used in the assembly.
• true_theta: the true_theta argument used in the assembly.
• data: the data argument used in the assembly.
• prior: the prior argument used in the assembly.
• prior_par: the prior_par argument used in the assembly.
• adaptivity: a list of adaptivity indices.
• simulation_constants: a list containing simulation constants parsed from input.
