The Oja median is one of several extensions of the univariate median to the multivariate case. It has many desirable properties, but is computationally demanding. In this paper, we first review the properties of the Oja median and compare it to other

We illustrate a novel data-driven way of visualizing paths of labor market transitions. The proposed technique is used in many fields of science when analyzing transitions longitudinally. The statistical method applied in this study is based on seque

In this paper we present a new method for testing multivariate growth curves which is based on spline approximation and on F-test. We show how the basic spline regression model can easily be extended to the multiple response case. The method is illus

In the several samples location problem, it is usually of interest to present estimates of treatment effects along with the test. The spatial Hodges–Lehmann estimators Δ ^ ij of the differences between treatments i and j are apparent companions to

Regression models have been used to control confounding in food borne cohort studies, logistic regression has been commonly used due to easy converge. However, logistic regression provide estimates for OR only when RR estimate is lower than 10%, an u

Summary In a modern computer-based forest harvester, tree stems are run in sequence through the measuring equipment root end first, and simultaneously the length and diameter are stored in a computer. These measurements may be utilized for example in

Two multivariate L 1 objective functions, namely the k–variate extensions of the classical mean deviation and mean difference, are considered. The duality between the original data vectors and the hyperplanes going through the origin and k – 1 da

The aim of this study was to investigate prediction of stem measurements of Scots pine(Pinus sylvestris L.) for a modern computerized forest harvester. We are interested in the prediction of stem curve measurements when measurements of stems already
