+ (description
+ "@code{dcor} is distance correlation and energy statistics in Python.
+
+E-statistics are functions of distances between statistical observations in
+metric spaces. Distance covariance and distance correlation are dependency
+measures between random vectors introduced in
+@url{https://github.com/vnmabus/dcor#srb07,[SRB07]} with a simple E-statistic
+estimator.
+
+This package offers functions for calculating several E-statistics such as:
+
+@itemize
+@item estimator of the energy distance
+@url{https://github.com/vnmabus/dcor#sr13,[SR13]}
+@item biased and unbiased estimators of distance covariance and distance
+correlation @url{https://github.com/vnmabus/dcor#srb07,[SRB07]}
+@item estimators of the partial distance covariance and partial distance
