AIPbootVrnc: Calculate variance of AIP using Bootstrapping.

In LDLcalc: Calculate and Predict the Low Density Lipoprotein Values

Calculate variance of AIP using Bootstrapping.

Description

This function can be used to calculate the variance of the Atherogenic Index of Plasma (AIP) using Bootstrapping.

Usage

AIPbootVrnc(
  TG,
  HDL,
  sampleSize = length(TG),
  SI = TRUE,
  noOfReps = 1000,
  pb = F
)

Arguments

TG	A vector or data frame column containing the triglyceride (TG) values to be used for the calculation of the variance of the Atherogenic Index of Plasma (AIP) using bootstrapping. TG and HDL must be of the same length.
HDL	A vector or data frame column containing the high density lipoprotein (HDL) values to be used for the calculation of the variance of the Atherogenic Index of Plasma (AIP) using bootstrapping. TG and HDL must be of the same length.
sampleSize	(default = length of TG or HDL) The sample size that will be generated at each bootstrapping sampling round. Size of bootstrapped samples cannot be larger than the original.
SI	Boolean (default=TRUE). AIP is by definition calculated using SI units for TG and HDL (mmol/L). If mg/dl units are provided instead, SI must be set to FALSE.
noOfReps	(default = 1000) Number of repetitions of the bootstrapping.
pb	Display a progress bar (default = FALSE)

Value

It returns a data table with four columns. The first column contains the mean of the AIP values for each iteration. The second column contains the median of each iteration.The third column contains the variance and the fourth column contains the CV of each iteration. It also returns the median of the "Mean", "Var" and "CV" columns of the data table.

Examples

## Not run: 
AIPbootstrVar = AIPbootVrnc(sampleA$TG,sampleA$HDL)
