The Statistics View in the RapidMiner Studio GUI gives such a summary, and this is very useful to get a sense of how big the data is and what its range is. This view is available to show example sets when the Results view is selected. It is always worthwhile to take a careful look at this view to check that the attributes are of the correct type. Numerical attributes should have an average and a standard deviation that looks sensible and nominal values should have a full set of valid values and dates within an expected range.
To force the macro to be treated as a string, place it in quotes. With the macro m1 equal to the string a1, the expression "%{m1}" + a2 would evaluate to "a1" + a2. xml is available with the files that accompany this book, which illustrates the previous example. A large number of functions are available and there is help available from the operator description as well as the Edit Expression dialog, which is accessed by pressing the button to the right of the function expressions in the previous screenshot.
Xml, the following graph shows att15 plotted as a function of time. The graph shows that there is some structure as a function of time but it can be difficult to interpret because there are so many data points: [ 39 ] Visualizing Data One approach to simplify this is to use the Moving Average operator to smooth the data out. This operator simply calculates a moving average for an attribute, given a window size, and creates a new example in the example set. xml is provided with this book to generate the result shown in the previous screenshot.
