LDLErrPrp {LDLcalc}

Calculate LDL variance using error propagation

Description

Function to calculate the LDL Variance according to error propagation (delta) method.

Usage

LDLErrPrp(CHOL, HDL, TG, divFactor = 5)

Arguments

CHOL

A vector containing the cholesterol values to be used for LDL calculation.

HDL

A vector containing the HDL values to be used for LDL calculation.

TG

A vector containing the triglyceride values to be used for LDL calculation.

divFactor

The factor by which to divide the triglyceride values so as to approximate the VLDL. Default is 5, according to the Friedewald equation.

Value

The function returns the error propagation variance of LDL calculated from the cholesterol, HDL and tryglyceride values passed as arguments.
