qtmean: Inverse cumulative distribution function for t distribution

In cdfinv: Confidence Interval Estimation via CDF Inversion

Inverse cumulative distribution function for t distribution

Description

Computes the value of sample mean corresponding to the input quantile p of the t distribution for n-1 degrees of freedom

Usage

qtmean(p, mean, s2, n)

Arguments

p	value of cdf (named in accordance with R standards)
mean	the assumed normal mean
s2	the observed sample variance (pass this as an extra argument to cdfinv())
n	the sample size (pass this as an extra argument to cdfinv())

Details

Do not call qtmean() directly. Pass DISTR="tmean" to cdfinv() when computing intervals for the normal mean when the variance is unknown. The parameter name to be passed to cdfinv() is mean. The additional arguments s2 (sample variance) and n (sample size) are to be passed to cdfinv().

Value

The value of sample mean corresponding to the input quantile p of the t distribution for n-1 degrees of freedom
