imputeConstant {BLOQ}

imputing BLOQ's with a constant value

Description

function to impute BLOQ observations by replacing them with a constant value.

Usage

imputeConstant(inputData, LOQ, constantValue)

Arguments

inputData

numeric matrix or data frame of the size n by J (n the sample size and J the number of time points) the input dataset

LOQ

scalar, limit of quantification value

constantValue

scalar, the constant value which replaces all BLOQ's, default is LOQ/2

Value

the imputed dataset: a numeric matrix or data frame of the size n by J (n the sample size and J the number of time points)

Examples

# generate data from Beal model with only fixed effects
set.seed(111)
genDataFixedEffects <- simulateBealModelFixedEffects(10, 0.693,
+ 		1, 1, seq(0.5,3,0.5))
# replacing BLOQ's with LOQ/2
imputeConstant(genDataFixedEffects, 0.1, 0.1/2)
