When using vector autoregressive (VAR) models for approximating time series, a key step is the selection of the lag length.Often this is performed using information criteria, even if a theoretical justification is lacking in some cases.For stationary processes, the asymptotic properties of the corresponding estimators Recorder Accessories are well

Using Recorder Accessories information on geomagnetic activity, sunspot numbers and cosmogenic isotopes, supported by historic eclipse images and in conjunction with models, it has been possible to reconstruct annual means of solar wind speed and number density and heliospheric magnetic field (HMF) intensity since 1611, when telescopic observations

Abstract Randomised trials with long-term follow-up can provide estimates of the long-term effects of health interventions.However, analysis of long-term outcomes in randomised trials may be complicated by problems with the administration of treatment such as non-adherence, treatment switching and co-intervention, and problems obtaining outcome mea

Process monitoring has played an increasingly significant role in ensuring safe and efficient manufacturing operations in process industries Toy over the past several years.Chemical process data is highly correlated and has multiscale characteristics in general.Extensive work has been carried out to overcome this concern for multiscale process moni
