correlation and regression hypothesis test calculator

If you would like to examine the formulas and technical details relating to a specific PASS procedure, we recommend you download and install the free trial of the software, open the desired correlation procedure, and click on the help button in the top right corner to view the complete documentation of the procedure. This page provides a brief description of the tools that are available in PASS software for sample size correlation and power analysis. A numeric summary of these results is produced along with easy-to-read sample size or power curve graphs. When this is done, estimates are made for every combination of entered values. For many of the parameters (e.g., power, alpha, sample size, correlation, etc.), multiple values may be entered in a single run. A summary statement is given, as well as references to the articles from which the formulas for the result were obtained. The procedure is run and the output shows a summary of the entries as well as the sample size estimate(s). In a typical correlation procedure where the goal is to estimate the sample size, the user enters power, alpha, and values related to correlation.

In the case of confidence intervals, one could solve for sample size or the distance to the confidence limit.

For more details about a topic, we recommend you download and install the free trial of the PASS software and utilize its correlation software. Only a brief summary is given for each procedure. Use the links below to jump to a correlation topic. Each procedure is easy-to-use and validated for accuracy. PASS also has procedures that compute sample size and power for testing one and two coefficient alphas, testing kappa for the agreement between two raters, and Lin’s concordance correlation coefficient. PASS contains several procedures for sample size calculation and power analysis for correlation, including tests for one and two correlations, confidence intervals for one correlation, and tests for intraclass correlation.
