A characteristics is a value or a group of values which describes a time series in a specified way.

In the TimeTransf module you must specify which computing function you want to use (for example: average, trend, –) and the variable (an attribute in the original analysed data) for which you want to compute the characteristics.

Later in data-minig process you use values of these characteristics instead of the original time series.
