Sample size and power calculations are available for one-sample and two-sample paired and independent designs, when the proposed analysis is construction of confidence intervals of a mean (one-sample) ...

The interval between the gridlines in an Excel chart is typically blank, but you can highlight the intervals using an alternating pattern by changing the formatting for the gridlines themselves.

For comparison of proportions, there are three commonly used measurements: the difference, the relative risk, and the odds ratio. Significant effort has been spent on exact confidence intervals for ...

In the estimation of error rates for populations, whose error rate is quite small, the usual assumption of normality can lead to erroneous results. The confidence ...

PROC GENMOD produces likelihood ratio-based confidence intervals, also known as profile likelihood confidence intervals, for parameter estimates for generalized linear models. These are not computed ...
