Concentration Index

Description

Calculates the Concentration Index (CI) on a daily precipitation serie.

Usage

...

a set of daily precipitation series.

Value

A data.frame containing the following variables:

  • dataset is the precipitation serie name.

  • a is the constant of the exponential curve defined via the least-squares method.

  • b is the constant of the exponential curve defined via the least-squares method.
