The vector autoregressive model has long been used for portfolio analysis, while a recent extension (VARX) incorporates exogenous factors. Despite its increased forecasting precision, the ...
A model with first-order autoregressive errors, AR(1), has the form while an AR(2) error process has the form and so forth for higher-order processes. Note that the ...
Impulse response functions from time series models are standard tools for analyzing the relationship between economic variables. The asymptotic distribution of orthogonalized impulse responses is ...
This paper derives the asymptotic mean square error of multistep prediction for the general vector autoregressive process. For one-step-ahead prediction the result is ...
Abstract: Electricity plays a very important role in daily modern human-life activities. An electricity company must always guarantee the continuity and adequate supply to its customers. Consequently, ...
Every time a language model like GPT-4, Claude or Mistral generates a sentence, it does something deceptively simple: It picks one word at a time. This word-by-word approach is what gives ...
