Compute Innocent Suspect ID Rate with No Correction — innocent_id_rate

Estimates innocent-suspect identification rate assuming all mistaken IDs are innocent-suspect IDs (no correction for lineup size).

Usage

innocent_id_rate_uncorrected(error_rate)

Arguments

error_rate: Numeric. Overall mistaken identification rate from culprit-absent lineups.

Value

Numeric. Estimated innocent-suspect identification rate (equal to error_rate).

Details

This represents the "worst case" estimate, treating every mistaken ID as an innocent-suspect identification. Provides an upper bound on innocent-suspect risk. The formula is simply: innocent_id_rate = error_rate
