CALC.forecast(x, known_y_values, known_x_values)

Calculates, or predicts, a future value by using existing values. The predicted value is a y-value for a given x-value. The known values are existing x-values and y-values and the new value is predicted by using linear regression. X is the data point for which you want to predict a value. Known_y_values is the dependent array or range of data. Known_x_values is the independent array or range of data.

Example

CALC.forecast(30, [6,7,9,15,21],[20,28,31,38,40]);

// returns 10.6072
