Remedies of autocorrelation

WebSingle particle orientation and rotational tracking (SPORT) has been proven to be a highly effective upgrade to the conventional single particle tracking (SPT) techniques for investigating nanoscale rotational dynamics in chemical and biological systems. Data analysis in SPORT is particularly important to extract useful information from the dynamic … WebThe presence of autocorrelation in the regression model can be dealt with in several ways. In case autocorrelation has arisen due to incorrect model specification then the most appropriate method is to specify the model correctly. This can be done by introducing the omitted variables or lagged dependent variables.
