%description
Aids in learning statistical functions incorporating the result of
calculus done with each function and how they are obtained, that is, which
equation and variables are used. Also for all these equations and their
related variables detailed explanations and interactive exercises are also
included. All these characteristics allow to the package user to improve
the learning of statistics basics by means of their use.
