ci {precintcon}

Concentration Index

Description

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

Usage

ci(..., interval = 1)

Arguments

interval

the interval in millimeters applied for calculating the concentration index. (Default value: 1)

...

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.

• r2 is the determination of coefficient of determination (R2) of the exponential model.

• A is the area over the exponential curve.

• S is the are compressed for the exponential curve.

• ci is the concentration index.
