In this phase, models can be adjusted and the best performing model selected. Trained models can then be applied to another partition - the validation partition - of the same data set to see how well they do with data that they were not trained with. For training a model, we usually choose (at random) a fraction of the available data - the training partition. Operations There are five broad groups of operations in XLMiner: Partitioning A data set with known values of an outcome (response) variable is necessary to train a data mining model. Exploring data in this fashion often yields quick insights about hidden relationships in the data, as well as "what is important, and what is not." This step can inform your choices of further operations, from data preparation and transformation to the fitting of data mining models. With a simple point and click, you can change axes or colors, or create multiple panels based on the values of any categorical variable.
You can use filters for each continuous and categorical variable - simple sliders and checkbox arrays that appear automatically in a side pane - to include or exclude points of interest. You can use your mouse to zoom in and out, or select points of interest in a given chart these points will be 'brushed' or highlighted in other charts in the same chart window, and the actual values of variables at each highlighted point are visible in scrollable side pane. Also available (with one click) are quick charts of all variables, scatterplot matrix charts, and parallel coordinates charts. In a chart window, you can create bar, line, scatterplot, boxplot, and histogram charts with one click.

You can create any number of chart windows (each containing multiple linked charts), name, and save these windows in the workbook. It is no longer necessary to use external tools such as Tableau or SpotFire to visualize your data this can be done easily and at no extra cost in XLMiner itself. Data Exploration and Visualization XLMiner V4.0 has built-in features for data exploration and visualization. However, the Educational edition limits the size of the database table or view from which you can sample, as well as the size of the sample drawn.

In XLMiner V4.0 (unlike earlier XLMiner versions), this feature is available in both the Professional edition and the Educational edition. XLMiner can sample data from Oracle, SQL Server and Access databases, and in V4.0 from PowerPivot in-memory databases. A standard procedure is to sample data from a larger database, bring it into Excel to fit a model, and, in the case of supervised learning routines, score output back out to the database. Databases, Spreadsheets and Size Limits XLMiner can work with large data sets which may exceed the limits in Excel. It is usually a good idea to try different approaches, compare their results, and then choose a model that suits the problem well. A problem or a data set can be analyzed by several methods. XLMiner provides a comprehensive set of analysis features based both on statistical and machine learning methods.
