GumbelEst: Gumbel distribution estimates from parameters

Description

Estimated quantiles as function of return period (RP) and vice versa, from user input parameters

Usage

GumbelEst(loc, scale, q = NULL, RP = 100)

Value

quantile as a function of RP or vice versa

Arguments

loc

location parameter

scale

scale parameter

q

quantile. magnitude of the variable under consideration

RP

return period

Author

Anthony Hammond

Details

If the argument q is used, it overrides RP and provides RP as a function of q (magnitude of variable) as opposed to q as a function of RP.

Examples

#Get an annual maximum sample, estimate the parameters and estimate 50-year RP
AM.27090 <- GetAM(27090)
Pars <- as.numeric(GumbelPars(AM.27090$Flow))
GumbelEst(Pars[1], Pars[2], RP = 50)
#Estimate the RP for a 600m3/s discharge
GumbelEst(Pars[1], Pars[2], q = 600)
