calc_absolute: Calculate absolute performance criteria and MCSE

Description

Calculates absolute bias, variance, mean squared error (mse) and root mean squared error (rmse). The function also calculates the associated Monte Carlo standard errors.

Usage

calc_absolute(
  data,
  estimates,
  true_param,
  criteria = c("bias", "variance", "stddev", "mse", "rmse"),
  winz = Inf
)

Value

A tibble containing the number of simulation iterations, performance criteria estimate(s) and the associated MCSE.

Arguments

data

data frame or tibble containing the simulation results.

estimates

vector or name of column from data containing point estimates.

true_param

vector or name of column from data containing corresponding true parameters.

criteria

character or character vector indicating the performance criteria to be calculated, with possible options "bias", "variance", "stddev", "mse", and "rmse".

winz

numeric value for winsorization constant. If set to a finite value, estimates will be winsorized at the constant multiple of the inter-quartile range below the 25th percentile or above the 75th percentile of the distribution. For instance, setting winz = 3 will truncate estimates that fall below P25 - 3 * IQR or above P75 + 3 * IQR.

Examples

calc_absolute(data = t_res, estimates = est, true_param = true_param)
