Accuracy {PowerSDI} | R Documentation |
Verify how well NASA-POWER Data Represent Observed Data
Description
Calculates scalar measures of accuracy.
Usage
Accuracy(obs_est, conf.int = "Yes", sig.level = 0.95)
Arguments
obs_est |
A 2-column matrix. The reference or observed and the estimated or predicted
data. See |
conf.int |
A character variable ( |
sig.level |
A numeric variable (between 0.90 and 0.95) defining the significance level for parameter the confidence intervals. Default is 0.95. |
Value
An object of class PowerSDI.Accuracy
, a list
, which contains:
Absolute mean error (AME),
square root of the mean squared error (RMSE),
Willmott's indices of agreement:
original (dorig),
modified (dmod) and
refined (dref)
Pearson determination coefficient (R2), and
if
conf.int = "Yes"
, confidence intervals.
Examples
a <- Accuracy(obs_est = ObsEst, conf.int = "No")
