computeConfidenceIntervalT {safestats}

Helper function: Computes the safe confidence sequence for the mean in a t-test

Description

Helper function: Computes the safe confidence sequence for the mean in a t-test

Usage

computeConfidenceIntervalT(
  meanObs,
  sdObs,
  nEff,
  nu,
  deltaS,
  ciValue = 0.95,
  g = NULL
)

Arguments

meanObs

numeric, the observed mean. For two sample tests this is difference of the means.

sdObs

numeric, the observed standard deviation. For a two-sample test this is the root of the pooled variance.

nEff

numeric > 0, the effective sample size. For one sample test this is just n.

nu

numeric > 0, the degrees of freedom.

deltaS

numeric > 0, the safe test defining parameter.

ciValue

numeric is the ciValue-level of the confidence sequence. Default ciValue=0.95.

g

numeric > 0, used as the variance of the normal prior on the population delta Default is NULL in which case g=delta^2.

Value

numeric vector that contains the upper and lower bound of the safe confidence sequence

Examples

computeConfidenceIntervalT(meanObs=0.3, sdObs=2, nEff=12, nu=11, deltaS=0.4)
