Easy Fit / Easy Predict
Use this feature to test and compare different predictive models for the same dataset. Available in Excel using the XLSTAT software.
Easy Fit allows you to test and compare different predictive models for the same dataset. Depending on the type of the dependent and explanatory variables (quantitative or qualitative), various models are proposed. The Easy Predict function can be then used to make predictions using the previously fitted models.

Results for the Easy Fit / Easy Predict function in XLSTAT
Descriptive statistics: The tables of descriptive statistics show basic statistics for all the selected variables such as the number of observations, missing values, the number of non-missing values, the mean and the standard deviation (unbiased) are displayed for the quantitative variables. For qualitative variables the names of the various categories are displayed together with their respective frequencies.
Summary table: The summary table contains the following indicators: MAE, MSE, R², adjusted R², AIC and SBC. Therefore for a classification, the indicators are: Accuracy, Precision, Recall, Correct classification number, Misclassification number and F-score (see Model Performance Indicators).
Summary results by method: For each method the most important results of the method are displayed. For a better understanding of the various results, you can access the help section of the related methods.
