Prediction Intervals

The prediction intervals are defined as follows:

• For m future observations:

for

• For the mean of m future observations:

for .

• For the standard deviation of m future observations:

for

where m = number of future observations, and n = number of points in current analysis sample.

• The one-sided intervals are formed by using 1-α in the quantile functions.
