Stable gradient-adjusted root mean square propagation on least squares problem ∗Runze Li† , Jintao Xu ‡ ,and Wenxun Xing §Abstract. Root mean square propagation (abbreviated as RMSProp) is a f i rst-order stochastic algorithm usedin machine learning widely. In this paper, a stable gr...
Next, all parameters related to hospital and ICU occupancy (including discharge rates) were estimated based on minimising a least squares criterion for the distance between the observed and generated loads. Finally, the estimated mortality-related parameters are inferred again using a likelihood-based ...

There are a considerable number of research studies on change-point detection. It is well-known that least-squares fitting, coupled with a dynamic programming (DP) algorithm (Fisher [14] and Bellman [3]), is the basic method from a practical perspective. Yao and Au [34] applied an informa...
A linear least squares trend line, created using the Excel trend line function (Red trace) shows a small temperature rise of 0.09C per century which is far less than the rise claimed by AGW supporters and clearly of no concern. However, the data shown in figure 5 bears little if any res...
For the analysis of length-of-stay (LOS) data, which is characteristically right-skewed, a number of statistical estimators have been proposed as alternatives to the traditional ordinary least squares (OLS) regression with log dependent variable. Using a
The challenge for such studies is to combine the health effects, caused by injuries, with the disease driven health effects, and to express the change in the health with a common health indicator. Disability-adjusted life year (DALY) combines years lived disabled or injured (YLD) and years ...

As this approach assumes cardinality of well-being, the weights are estimated with ordinary least squares regressions. Generally speaking, methods used in SWV either assume the cardinality or only ordinality of the well-being scale (MacKerron, 2012). However, Ferrer‐i‐Carbonell and Frijters (...
