imputeConstant {BLOQ} | R Documentation |
function to impute BLOQ observations by replacing them with a constant value.
imputeConstant(inputData, LOQ, constantValue)
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 |
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)
