Resumen de Random variable functions used in hydrology

Cira E. G. Otiniano, Yuri S. Maluf

• In this work, expressions of the cumulative distribution function of Y X, Y/X and X/(X + Y ) for continuous dependent random variables with supported on a unbounded and bounded interval are derived. The dependence approach is based on copula functions. Additionally, the methodology is applied to real data on hydrology.
