Estimating the mean effect size in meta-analysis: Bias, precision, and mean squared error of different weighting methods [PDF]

open access: yesBehavior Research Methods, Instruments, & Computers, 2003
Although use of the standardized mean difference in meta-analysis is appealing for several reasons, there are some drawbacks. In this article, we focus on the following problem: that a precision-weighted mean of the observed effect sizes results in a biased estimate of the mean standardized mean difference.

On the influence of detection tests on deterministic parameters estimation [PDF]

open access: yes, 2006
In non-linear estimation problems three distinct regions of operation can be observed. In the asymptotic region, the Mean Square Error (MSE) of Maximum Likelihood Estimators (MLE) is small and, in many cases,close to the Cramer-Rao bound (CRB).

Assessment of spatial interpolation techniques for drought severity analysis in Salt Lake Basin [PDF]

open access: yesDesert, 2021
Drought risk management requires drought monitoring which is usually carried out by applying different drought indices which are, effectively, continuous functions of precipitation and other meteorological data.

The Least Square and the Weighted Least Square Methods for Estimating the Weibull Distribution Parameters - A Comparative Study [PDF]

open access: yes, 2012
In this paper we study the performance of the least square method and the weighted least square method for estimating the Weibull distribution parameters. In engineering practice these methods are commonly used due to their simplicity.

Indicators for evaluation of model performance: irrigation hydraulics applications

open access: yesActa Scientiarum. Agronomy, 2022
Several mathematical models have been developed for applications in the hydraulics of irrigation systems and several performance indicators of these models are used and suggested by the literature. Thus, the objective of this work was to investigate the

PTRNet: Global Feature and Local Feature Encoding for Point Cloud Registration

open access: yesApplied Sciences, 2022
Existing end-to-end cloud registration methods are often inefficient and susceptible to noise. We propose an end-to-end point cloud registration network model, Point Transformer for Registration Network (PTRNet), that considers local and global features ...

Bootstrap Approximation to Prediction MSE for State-Space Models with Estimated Parameters [PDF]

open access: yes, 2004
We propose a simple but general bootstrap method for estimating the Prediction Mean Square Error (PMSE) of the state vector predictors when the unknown model parameters are estimated from the observed series.

Leave-one-out cross validation mean square error values for model fits of the spiking nonlinearity. [PDF]

open access: yes, 2021
The leave-one-out cross validation mean square error measures the accuracy of the model fit on data not used in the model fit, to avoid overfitting the data (see Materials and methods). (PNG)
