Compare EQC and SPC Calibration Results — compare_eqc_spc • IRTsimrel

Compares the calibration results from EQC and SPC algorithms.

Usage

compare_eqc_spc(eqc_result, spc_result, verbose = TRUE)

Arguments

eqc_result: An object of class "eqc_result".
spc_result: An object of class "spc_result".
verbose: Logical. If TRUE, print comparison summary.

Value

A list with comparison statistics (invisibly):

c_eqc: Calibrated c* from EQC.
c_spc: Calibrated c* from SPC.
diff_abs: Absolute difference between c* values.
diff_pct: Percent difference relative to EQC.
agreement: Logical. TRUE if difference is < 5%.
target_rho: Target reliability.
