PRSim (version 1.1)

simulations: Simulated runoff

Description

The dataset is generated with the package own routines and represent 50 series of 18 years of runoff

Usage

data("simulations")

Format

A list of three elements, containing (i) a data frame with 6570 observations of the following 56 variables

YYYY

a numeric vector, year

MM

a numeric vector, month

DD

a numeric vector, day

timestamp

POSIXct vector of the daily runoff

deseasonalized

deseasonalized time series

Qobs

observed runoff

r1,…,r50

50 simulated runoff series

(ii) a data frame with the daily fitted kappa parameters and (iii) p-values of the daily ks.test.

Details

The data is included to illustrate the validation and visualization routines in demo("PRSim-validate").
