Intuitive Sample Size & Power Calculator
Calculate sample size and conduct a power analysis with a clean & easy to use interface
So whether you're planning to do a simple t-test analysis, you want to undertake a complex simulation of a survival study when planning it, or you wish to take advantage of interim monitoring in a group sequential design.
Another example is in a group sequential table you'll be provided with a boundary plot which gives the boundaries of rejection for futility or efficacy at each time point.
Specify Multiple Factors
The specify multiple factors tool allows you to quickly and efficiently explore a number of scenarios in your sample size table.
The output statement is a verbal summary of the sample size determination results that you calculated in nQuery. This can then provide a template which can be added to your study protocol or study proposal and then edited to reflect the specifics of your trial.
，专注，专心是科学软件网的服务宗旨，开发的软件、传递*的技术、提供贴心的服务是我们用实际行动践行的目标，我们会为此目标而不懈努力。
