We computed the effective sample size and statistical power using Genetic Power Calculator. An analysis using a larger number of markers requires a larger sample size. Testing a single-nucleotide polymorphism (SNP) marker requires 248 cases, while testing 500,000 SNPs and 1 million m...
Sample Size Calculator You want to hit statistical reliability – fast. Figure out how big your A/B test sample size needs to be with our A/B test calculator. No Mathematics PhD required. When runningA/B teststo improve your conversion rate, it is highly recommended to calculate asample ...
This calculator will tell you the observed power for your multiple regression study, given the observed probability level, the number of predictors, the observed R2, and the sample size.
Sample Size Software PASS is the world-wide leading software tool for determining sample size. As the leader in sample size technology, PASS performs power analysis and calculates sample sizes for over 1100 statistical test and confidence interval scenarios. ...
The Cumfreq calculator model not only uses logarithmic but also exponential transformations of the data where the exponent (greater than 0) is optimized automatically and these so called generalized distributions have great flexibility, but… Overview Features • An input menu for data handling • ...
