The EM Algorithm [PDF]

open access: yes
The Expectation-Maximization (EM) algorithm is a broadly applicable approach to the iterative computation of maximum likelihood (ML) estimates, useful in a variety of incomplete-data problems.

Exact maximum-likelihood method to detect patterns in real networks [PDF]

open access: yes
In order to detect patterns in real networks, randomized graph ensembles that preserve only part of the topology of an observed network are systematically used as fundamental null models. However, their generation is still problematic.

Comparison between Linear Regression and Robust Regression Models by Using Error Criteria and Information Criteria Applied to Human Sample

open access: yesZanco Journal of Humanity Sciences
Hypertension is a common and serious disease, and for this reason, a sample of patients was chosen from Azadi Teaching Hospital in Duhok. In this study a comparison was made between Ordinary Least Squares (OLS) with two robust methods Least Trimmed ...

A note on forecasting demand using the multivariate exponential smoothing framework

open access: yes, 2014
Simple exponential smoothing is widely used in forecasting economic time series. This is because it is quick to compute and it generally delivers accurate forecasts.

A Distance-Based Maximum Likelihood Estimation Method for Sensor Localization in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2016
Node localization is an important supporting technology in wireless sensor networks (WSNs). Traditional maximum likelihood estimation based localization methods (MLE) assume that measurement errors are independent of the distance between the anchor node ...

Weibull-Fréchet distribution: A new lifetime distribution with application to gastric cancer data [PDF]

open access: yesITM Web of Conferences
Lifetime data is a type of data that consists of waiting time until an event occurs. Some of the events of lifetime data are deaths, occurrence of a disease, or failure of a machine. The distribution usually used for modeling lifetime data is the Weibull
