An array of the backtests performed to evaluate the accuracy of the predictor against a particular algorithm. The
<code>NumberOfBacktestWindows</code> from the object determines the number of windows in the array.

@param predictorExecutions
       An array of the backtests performed to evaluate the accuracy of the predictor against a particular
       algorithm. The <code>NumberOfBacktestWindows</code> from the object determines the number of windows in
       the array.
@return Returns a reference to this object so that method calls can be chained together.
