Corr {SpecsVerification}

Calculate correlation between forecasts and observations, and assess uncertainty

Description

Calculate correlation between forecasts and observations, and assess uncertainty

Usage

Corr(fcst, obs, N.eff = NA, conf.level = 0.95, handle.na = "na.fail")

Arguments

fcst

vector of forecasts

obs

vector of observations

N.eff

user-defined effective sample size to be used in hypothesis test and for confidence bounds; if NA, the length of 'obs' is used after removing missing values; default: NA

conf.level

confidence level used the confidence interval; default = 0.95

handle.na

how should missing values in forecasts and observations be handled; possible values are 'na.fail' and 'use.pairwise.complete'; default: 'na.fail'

Value

vector with correlation, one-sided p-value, and central confidence interval at the user-defined confidence level
