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 |
