Web11 de abr. de 2016 · I'm working in SAS, and I've tried doing research on this, but for me, matrix algebra is really scary (I tried things like 'Game-Theoretically Optimal Reconciliation of Contemporaneous Hierarchical Time Series Forecasts'). I'm just a mortal and I don't know how to incorporate these kinds of formulae into my SAS coding. WebThis step detrends the data. The default trend model for the STEPAR method is TREND=2, a linear trend model. Take the residuals from step 1 and compute the autocovariances to the number of lags specified by the NLAGS= option. Regress the current values against the lags, using the autocovariances from step 2 in a Yule-Walker framework.
