stdRecal {ClinicalUtilityRecal}

Standard Logistic Recalibration

Description

Produces recalibration intercept, slope and corresponding recalibrated risk scores using standard logistic rexalibration. Recalibration slope and intercept using logistic recalibration method, develop by Cox (1958), then used to calculated the recalibrated risk score

Usage

stdRecal(y,p)

Arguments

y

Vector of binary outcomes, with 1 indicating event (case) and 0 indicating no event (controls)

p

Vector of risk score values

Value

stdRisk

Vector of recalibrated risks under standard logistic recalibration

alpha

Two-element vector containing logistic recalibration intercept and slope
