Stationarity of a series
These are where the mean, variance and autocorrelation structures in a model do not change over time. It is a stochastic process whose joint distribution in probability does not change even when shifted in time. The statistical properties do not change over time. It shows that the degrees of expectation, third order and the variance do not change in the process of estimation.
Benefits of stationarity of a series
Stationarity a series has several benefits. To begin with, the study of behavior for a certain period under consideration is made easy due to the consistency in the model. In the forecasting of the expected results are more likely to ...
