Field Value
A double containing the confidence level of the variance.
Remarks
Under the assumption of equal variances, the pooled variance is used
to obtain a two-sided ConfidenceVariance percent confidence
interval for the common variance with
LowerCICommonVariance or
UpperCICommonVariance. Without making the
assumption of equal variances,
UnequalVariances,
the ratio of the variances is of interest. A two-sided
ConfidenceVariance percent confidence interval for the ratio
of the variance of the first sample to that of the second sample is
given by the LowerCIRatioVariance and
UpperCIRatioVariance. See
UnequalVariances and
UpperCIRatioVariance
. The confidence intervals are symmetric in probability.
ConfidenceVariance must be between 0.0 and 1.0 and is often
0.90, 0.95 or 0.99. The default is 0.95.
