In blebedenko/thescript2: Boris's thesis scripts

Description

Atomic simulation of AUC coverage experiment with undersmoothing

Usage

AtomicSim.US(
  distribution,
  n,
  AUC,
  theta_squared,
  var_eq,
  ME_var_ratio,
  R = 1000,
  US_ratio = c(0.5, 0.25)
)

Arguments

distribution	one of the following strings : "normal", "gamma.skewed", "gamma.symmetrical" , "log.normal", "bimodal1", "bimodal2", "t3", "laplace", "cauchy"
n	number of observations in each group
AUC	the probability P(X>Y) of correctly ranking a pair of random observations (diseased,healthy).
theta_squared	contamination parameter (noise/signal)
var_eq	logical - if TRUE VX=VY=1, if FALSE VX=2VY=2 ratio of the biomarker variances
ME_var_ratio	(defaults to 1) the ration between ME variances, V
R	bootstrap replications (defaults to 1000)
US_ratio	vector of multipliers for the undersmoothing of bootstrap samples (defaults to 0.5,0.25)

Details

This is the doOne function required by simsalapar for parallel simulations.

Value

a vector of the point estimate and percentile CI and also the original observations,all concatenated in a named vector.

Examples

AtomicSim("gamma.skewed",250,0.8,0.5,TRUE,1,R=1000)
