Regular D-optimal weighing designs with negative correlations of errors: new classes
Journal Title: Colloquium Biometricum; Colloquium Biometricum (Online) - Year 2017, Vol 47, Issue
Abstract
In this paper, the properties of the regular D-optimal chemical balance weighing design are considered. We consider this design under assumption that the measurements errors are equally negative correlated they have the same variances. Here we study the issues regard to the existence conditions of regular D-optimal design. We present the relations between the parameters of such design and construction methods.

The growth curve model with heterogenous fractional decreasing correlation structure
In this text we will derive estimators of unknown parameters for growth curve model with different decrease of dependency in groups and we will compare them for the case of two groups. We will use method of maximum likel...
RANDOM FORESTS SUPPLEMENTED BY PARALLEL FENCES PLOTS: A STUDY IN SPIROMETRIC DIAGNOSTICS
We try to assess, what truly can be obtained when using only the spirometric measurements for the diagnosis of pulmonary disorders. Using spirometric data recorded for 202 patients and the Random Forests methodology, we...
COMPARISON OF PARMESAN CHEESE DRYING COURSE BY MEANS OF REGRESSION METHODS
The aim of the article is to compare regression lines which describe relations between the inverse of water content in cheese and time of drying. Each line involves one of the combinations of Parmesan’s type cheese piece...
A REMARK ON ESTIMATING DEFECTIVENESS IN SAMPLING ACCEPTANCE INSPECTION
Summary The problem of estimating a probability of success in a Binomial model is considered. The classical estimator is compared with the estimator which uses the information about non-homogeneity of the sample. An appl...
THE EFFECT OF THE ORCHARD HABITAT STRUCTURE AND YEAR ON APPLE CLEARWING MOTH S. MYOPAEFORMIS ABUNDANCE
In years 2008-2010 in orchard habitat near Czempiń in south Wielkopolska a mass appearance of apple clearwing moth Synanthedon myopaeformis and his larval ectoparasitoid Liotryphon crassiseta was stated. There were 7960...
