Improved maximum likelihood estimators in a heteroskedastic errors-in-variables model

open access: yes, 2011
This paper develops a bias correction scheme for a multivariate heteroskedastic errors-in-variables model. The applicability of this model is justified in areas such as astrophysics, epidemiology and analytical chemistry, where the variables are subject ...

The Burr XII-Burr XII Distribution: Mathematical Properties and Characterizations [PDF]

open access: yes, 2019
We introduce a new continuous distribution called the Burr XII-Burr XII distribution. Some of its properties are derived. The method of maximum likelihood is used to estimate the unknown parameters.

Verification of Magnitude and Phase Responses in Fixed-Point Digital Filters

open access: yes, 2017
In the digital signal processing (DSP) area, one of the most important tasks is digital filter design. Currently, this procedure is performed with the aid of computational tools, which generally assume filter coefficients represented with floating-point ...

Human Associations Help to Detect Conventionalized Multiword Expressions

open access: yes, 2017
In this paper we show that if we want to obtain human evidence about conventionalization of some phrases, we should ask native speakers about associations they have to a given phrase and its component words.

Biological properties of extracellular vesicles and their physiological functions

open access: yesJournal of Extracellular Vesicles, 2015
In the past decade, extracellular vesicles (EVs) have been recognized as potent vehicles of intercellular communication, both in prokaryotes and eukaryotes. This is due to their capacity to transfer proteins, lipids and nucleic acids, thereby influencing

The distribution of Pearson residuals in generalized linear models

open access: yes, 2008
In general, the distribution of residuals cannot be obtained explicitly. We give an asymptotic formula for the density of Pearson residuals in continuous generalized linear models corrected to order $n^{-1}$, where $n$ is the sample size.
