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).
Source
The file cascades.dat in the LMOMENTS Fortran package (Hosking, 1996).
