TīmeklisCalculate a lag-1 residual variable, lagRESI. Fit a simple linear regression model with response RESI and predictor lagRESI and no intercept. The estimated slope from this regression, 0.631164, is an estimate of the autocorrelation parameter, \(\rho\). TīmeklisNote the confidence intervals in Python are calculated differently via Bertlett’s formula, which is under the alternative hypothesis, that serial correlation exists up to lag \(k-1\).. We can see from the plots that there are some sample autocorrelations \(\widehat{\rho}(k)\), which are statistically significantly different from zero (i.e. their …

Tīmeklis2024. gada 24. febr. · We predict the residuals of the difference model. We regress the predicted residual over the first lag of the predicted residual.
