Align the distribution of one empirical distribution to an empirical reference distribution

Description

Align the distribution of one empirical distribution to an empirical reference distribution

Usage

e_scale_align(
  var_to_scale = NULL,
  var_ref = NULL,
  scale_method = c("quantile", "zscore")[1],
  quantiles_to_match = c(0.1, 0.9),
  sw_plot = c(TRUE, FALSE)[2]
)

Arguments

var_to_scale	Variable to rescale
var_ref	Reference variable distribution
scale_method	Method of rescaling. "quantile" with c(0.1, 0.9) is remarkably good.
quantiles_to_match	For "quantile", which quantiles to match.
sw_plot	T/F to plot Reference, Original, and Scaled variables.

Value

var_scaled Scaled vector (NAs have been removed)

Examples

set.seed(76543)
e_scale_align(
  var_to_scale        = c(NA, rgamma( 40, shape = 3, rate = 2) + 4, NA)
, var_ref             = rgamma(100, shape = 3, rate = 1)
, scale_method        = c("quantile", "zscore")[1]
, quantiles_to_match  = c(0.1, 0.9)
, sw_plot             = c(TRUE, FALSE)[1]
)
