Welcome to *cocor*! This is a website allowing to conduct statistical comparisons between correlations. Click "Start analysis" to begin!

The calculations rely on the tests implemented in the package *cocor* for the R programming language. An article describing cocor and the cocor R package documentation are available. Here you find an overview of all implemented tests.

You can integrate the R code generated by this web interface in your own R script. To do so, you can download the *cocor* package from here or r-project.org. Alternatively, you can type one of the following commands in the R console to install:

install.packages("cocor", lib="/my/own/R-packages/")

# alternative repository

install.packages("cocor", lib="/my/own/R-packages/", repo="http://comparingcorrelations.org/repo")

The *cocor* package also includes a GUI extension for the R front-end RKWard, which you can use instead of this web interface.
