In ronkeizer/vpc: Create Visual Predictive Checks

Check and standardize limits of quantification

Description

Check and standardize limits of quantification

Usage

define_loq(
  lloq = NULL,
  uloq = NULL,
  pred_corr = FALSE,
  pred_corr_lower_bnd = 0,
  require_loq
)

Arguments

lloq	Number or NULL indicating lower limit of quantification. Default is NULL.
uloq	Number or NULL indicating upper limit of quantification. Default is NULL.
pred_corr	perform prediction-correction?
pred_corr_lower_bnd	lower bound for the prediction-correction
require_loq	Is at least one of lloq or uloq required?

Value

A list with elements "lloq", "uloq", "cens_limit", "pred_corr", "pred_corr_lower_bnd", and "cens_type". "cens_limit" indicates the range for censoring (c(lloq, uloq), NULL if neither is given), "cens_type" indicates whether the data are "left" censored (low values are censored, only), "right" (high values are censored, only), "both" (low and high values are censored), or "neither" (no values are censored).
