Lecture 6 Forecasting minimum mean squared errors

The Root Mean Square calculates the effective rate or measurement of a varying set of values. It is the square root of the average of the squared values in a data set. RMS is primarily used in physics and electrical engineering. One of the more common uses for an RMS calculation is comparing alternating current and direct current electricity.
