Using the classical linear regression model in analysis of the dependences of conveyor belt life [PDF]

open access: yesActa Montanistica Slovaca, 2013
The paper deals with the classical linear regression model of the dependence of conveyor belt life on some selected parameters: thickness of paint layer, width and length of the belt, conveyor speed and quantity of transported material. The first part of

Quantifying residual finiteness

open access: yesJournal of Algebra, 2010
We introduce the concept of quantifying the extent to which a finitely generated group is residually finite. The quantification is carried out for some examples including free groups, the first Grigorchuk group, finitely generated nilpotent groups, and certain arithmetic groups such as $SL_n(\mathbb{Z})$.

The extreme residuals in logistic regression models [PDF]

open access: yes, 1985
Goodness of fit tests for logistic regression models using extreme residuals are considered. Moment properties of the Pearson residuals are developed and used to define modified residuals, for the cases when the model fit is made by maximum ...

New Quantile Regression Model for Unit Interval Regressands

open access: yesEngineering Reports
This paper contributes significantly to regression analysis in that the authors have proposed a new and modern quantile regression (QR) model, which focuses exclusively on targeting regression analysis response variables that have a range on the unit ...
