pnormvar: Cumulative distribution function for t distribution
In cdfinv: Confidence Interval Estimation via CDF Inversion
pnormvar R Documentation
Cumulative distribution function for t distribution
Description
Computes the quantile of the chi-square distribution for n-1 degrees of freedom corresponding to the input value of the sample variance.
Usage
pnormvar(q, sigma2, n)
Arguments
q
coordinate at which the cdf is to be evaluated (named in accordance with R standards)
sigma2
the assumed normal variance
n
the sample size (pass this as an extra argument to cdfinv())
Details
Do not call pnormvar() directly.
Pass DISTR="normvar" to cdfinv() when computing intervals for the
normal variance.
The parameter name to be passed to cdfinv() is sigma2.
The additional argument n (sample size) is to be passed to cdfinv().
Value
The quantile of the chi-square distribution for n-1 degrees of freedom corresponding to the input value of the sample variance.

cdfinv("normvar","sigma2",14.35,lpb=0,n=22) ## returns 8.493787 29.305942
