This app helps you to explore and analyze your single-case experimental design (SCED) data with R.

Getting started

By going over the tabs in the top navigation bar one by one, you can analyze your SCED dataset step by step. Start by uploading a data file in the Input tab and assign the variables. Indicate which variables you want to include and prepare your data for analysis. Define the regression models for analysis in the Model tab. Perform a simple linear regression analysis per case in the One-level analysis tab. Perform a two-level analysis per study (if applicable) in the Two-level analysis tab. Perform a three-level (meta-)analysis in the Three-level analysis tab.
