Statistical Tools

What Statistical Calculators do you have at your website?

I currently have calculators on early phase single sample clinical trials with a survival endpoint, on the Cochran-Armitage trend test, on conditional power calculations, on the sample size for logistic regression, on the influence of large strata or sites in clinical trials, on power assessments for observational studies and on sample size and power for matched case-control and cohort studies. The calculations themselves can be worked out in a few hours to a day. However there is a need to dig out the appropriate reference, maybe pay for it, read and figure out the results and write code to calculate and check the results – all of which could take a little time and effort.

What other statistical content do you have at your website?

We have a set of calculators at this page to help you evaluate the merit of reported statistical inferences given a non-replicability epidemic in published data. I have written up helpful statistical pieces including one on a guide to the uninitiated clinical trial statistician, a little stats 101 for observational studies, and a write-up on ecological fallacies in clinical statistics.

What other content is at your site?

Some other commentaries not related to statistics include  a riff on the universe as a simulation, a discussion on guided meditation, details on the enneagram personality profile, a poem on the coming of spring, on profiling, and on artificial intelligence. We have financial advice offerings described at this page and details on  graphical tools here.
