You can open the resid sequence in eviews, select the differential order as level, and only look at the size of the accompanying p value. If the adjoint p value is large, the corresponding white noise is also large.

As long as the spectral width of a noise process is much larger than the bandwidth of the system it acts on, and its spectral density can be regarded as a constant within this bandwidth, it can be treated as white noise.

The basic data object that Eviews processes is time series, and each series has a name. As long as the name of the series is mentioned, all the observed values in the series can be operated. Eviews allows users to input data from keyboard or disk files in a simple and intuitive way.

Generate a new sequence according to the existing sequence, and display the sequence on the screen or print it on the printer, and statistically analyze the relationship between the sequences.
