Cascades: L-moments of annual precipitation totals

Description

\(L\)-moments of annual precipitation totals for the “North Cascades” region of Plantico et al. (1990).

Usage

Cascades

Format

An object of class regdata. It is a data frame with 19 observations on the following 7 variables:

name

Character vector: site identifier.

n

Numeric vector: record length.

mean

Numeric vector: sample mean.

t

Numeric vector: sample \(L\)-CV.

t_3

Numeric vector: sample \(L\)-skewness.

t_4

Numeric vector: sample \(L\)-kurtosis.

t_5

Numeric vector: sample \(L\)-moment ratio \(t_5\).

Details

The data are summary statistics of annual precipitation totals at 19 sites in the northwest U.S., the “North Cascades” region of Plantico et al. (1990). The precipitation data were obtained from the Historical Climatology Network (Karl et al., 1990).
