sse: Sample Size Estimation with R

Sample size must be estimated early – sse prepares you for multiple scenarios

What it is:

sse is a R statistics package with flexible tools for calculating sample size and presenting the statistics that relate power, sample size, and the assumptions made.

What it can do:

sse allows you to calculate the sample size of your clinical research project for multiple scenarios. The package can evaluate user-defined power functions for a range of parameters and can draw a figure illustrating the relation between power, sample size and the assumptions made. It also provides a resampling procedure for semi-parametric sample size estimation and methods for adding information to dynamic reports using Sweave.

Who should use it:

This tool is for statisticians or principal investigators planning a clinical research project or testing its feasibility.

Who is behind this resource:

The code was developed by statisticians at the CTU Basel on behalf of the SCTO’s Statistics & Methodology Platform. It is one of the winning projects of the platform’s statistical programming grant from 2018.
