hi {riskyr}R Documentation

Frequency of hits or true positives (TP).

Description

hi is the frequency of hits or true positives (TP) in a population of N individuals.

Usage

hi

Format

An object of class numeric of length 1.

Details

Definition: hi is the frequency of individuals for which Condition = TRUE and Decision = TRUE (positive).

hi is a measure of correct classifications, not an individual case.

Relationships:

  1. to probabilities: The frequency hi depends on the sensitivity sens (aka. hit rate or true positive rate, TPR) and is conditional on the prevalence prev.

  2. to other frequencies: In a population of size N the following relationships hold:
