In SPOT: Sequential Parameter Optimization Toolbox

spotPlotErrors

Description

Visualize the alpha, beta errors and the power of the test

Usage

spotPlotErrors(
  alternative = "greater",
  lower = -3,
  upper = 3,
  mu0 = 0,
  mu1 = 1,
  sigma = 1,
  n = NULL,
  xbar = 0,
  alpha = 0.05,
  beta = NULL
)

Arguments

alternative	One of greater, less, or two.sided. The greater is the default.
lower	lower limit of the plot
upper	upper limit of the plot
mu0	mean of the null
mu1	mean of the alternative. See also parameter beta.
sigma	standard deviation
n	sample size
xbar	observed mean
alpha	error of the first kind
beta	error 2nd kind. Default NULL. If specified, then parameter mu1 will be ignored and mu1 will be calculated based on beta.

Value

description of return value

Examples

spotPlotErrors(lower=490,upper=510,mu0=500,mu1=504,sigma=2.7,n=9,xbar=502.22)
spotPlotErrors(lower=140,upper=155,mu0=150,mu1=148,sigma=10,n=100,xbar=149,alternative="less")
