Total number of samples used. Double Root mean square standardized Root Mean Square Standardized Error—This whag be close to 1 if the prediction standard errors are valid.

Removes one data location and predicts the associated data using the data at the rest of the locations. The primary use for this tool is to compare the predicted value to the observed value in order to obtain useful information about some of your model parameters. Learn more about performing cross validation and validation.

When using this tool in Python, the result object contains both a feature class and a CrossValidationResultwhich has the following properties:. Count—Total number of samples used. Mean Error—The averaged difference between the measured and the predicted values. Root Mean Square Error—Indicates how closely your model predicts the measured values. The smaller this error, the better. Average Standard Error—The average of the prediction standard errors.

Mean Standardized Error—The average of the standardized errors. Stqndard value should be close to 0. Root Mean Square Standardized Error—This should be close to 1 if the prediction standard errors are valid. If the root-mean-squared standardized error id greater than 1, you are underestimating the variability in your predictions. If the root-mean-square-standardized error is less than 1, you are overestimating the variability in your predictions.

This value should be close to The CRPS is a diagnostic that measures the deviation from the predictive cumulative distribution function to each observed data value. This value should be as small as possible. This diagnostic has advantages over other cross-validation diagnostics because it compares the data to what is the standard error of the mean formula full distribution rather than to single-point predictions. The calculation of this statistic involves simulations so it cannot be written in a simple formula.
