Despite the global transition to green transportation, the adoption of electric and hybrid vehicles (E&HVs) in Qatar remains limited. This study examines the factors influencing youth intentions to buy E&HVs, employing the Theory of Planned Behavior (TPB) and assessing the mediating roles of...

Financial assets often exhibit explosive price surges followed by abrupt collapses, alongside persistent volatility clustering. Motivated by these features, we introduce a mixed causal-noncausal invertible-noninvertible autoregressive moving average generalized autoregressive conditional...

The Decline Curve analysis of the oil and gas wells model examines the production forecasting for oil and gas wells, i.e., the exponential decline curve. The standard equation, q = qie-at (3.3), can be used with random variables for both qi (the initial production rate, sometimes called IP) and...

This paper is concerned with the choice of data granularity for application of the EDF (Exponential Dispersion Family) chain ladder model to forecast a loss reserve. As the duration of individual accident and development periods is decreased, the number of data points increases, but the...

We propose using a discounted version of a convex combination of the log-likelihood with the corresponding expected log-likelihood such that when they are maximized they yield a filter, predictor and smoother for time series. This paper then focuses on working out the implications of this in the...
