Iterative method for exponentially weighted rolling regression

Forecasting daily supermarket sales using exponentially weighted quantile regression

Inventory control systems typically require the frequent updating of forecasts for many different products. In addition to point predictions, interval forecasts are needed to set appropriate levels of safety stock. The series considered in this paper are characterised by high volatility and skewness, which are both time-varying. These features motivate the consideration of forecasting methods t...

An iterative approach for estimation of efficiency by weighted distance

Traffic Optimization with Iterative Weighted Scheduling Method

In the future most communication networks (wireless and wired) will be required to provide support to a number of different types of traffic, each with it’s own particular characteristics and quality of service parameters including e.g. guaranteed bandwidth, jitter, and latency. The customers of different classes pay different prices to the service provider, who must share resources in a plausi...

An accelerated iterative method for computing weighted Moore-Penrose inverse

The goal of this paper is to present an accelerated iterative method for computing weighted Moore–Penrose inverse. Analysis of convergence is included to show that the proposed scheme has sixth-order convergence. Using a proper initial matrix, a sequence of iterates will be produced, which is convergent to the weighted Moore–Penrose inverse. Numerical experiments are reported to show the effici...
