In statpsych: Statistical Methods for Psychologists
ci.var.upper R Documentation
Upper confidence limit of variance
Description
Computes an upper limit for a population variance using an estimated variance
from a sample of size n in a prior study. The upper limit can be used as
a variance planning value in sample size functions that require a variance
planning value.
Usage
ci.var.upper(alpha, var, n)
Arguments
alpha
alpha value for 1-alpha confidence (one-sided)
var
estimated variance
n
sample size
Value
Returns an upper limit (UL) variance planning value
Examples
ci.var.upper(.25, 15, 60)
# Should return:
# UL
# 17.23264
