It does this by comparing the prediction errors of the two models around a specific time period. The exam checks the null speculation which the two versions have the identical efficiency on average, in opposition to the choice that they do not. If the examination statistic exceeds a critical worth, we reject the null hypothesis, indicating that the primary difference inside the forecast accuracy is statistically major.
If the size of seasonal read more alterations or deviations within the trend?�cycle stay regular regardless of the time sequence degree, then the additive decomposition is ideal.
, is surely an extension of your Gaussian random wander procedure, through which, at each time, we may well take a Gaussian move by using a likelihood of p or stay in a similar condition with a probability of 1 ??p
