An accurate forecast of Emergency Department (ED) arrivals by an hour the day is critical to meet patients’ demand. It enables planners match ED staff number arrivals, redeploy staff, and reconfigure units. In this study, we develop a model based on Generalised Additive Models advanced dynamic exponential smoothing generate hourly probabilistic for prediction window 48 hours. We compare accurac...

A time and frequency-domain analysis is made of the effects of averaging and sampling methods used for constructing magnetic-observatory hourly data values. Using 1min data as a proxy for continuous, geomagnetic variation, we construct synthetic hourly values of two standard types: instantaneous “spot” measurements and simple 1-h “boxcar” averages. We compare these average-sample types with oth...

A number of jurisdictions are installing or have installed interval meters for a large fraction or all of their retail customers. With this technology in place, the only remaining barrier is whether state regulators will ...
