The resolution of a set of n tests o r other var ia tes into components 7~, each of which accounts for the greates t possible port ion 71, ~,~, . , of the total variance of the tests unaccounted for by the previous components, has been dealt with by the author in a previous paper (2). Such "factors ," on account of their analogy with the principal axes of a quadric, have been called principal c...

Sections 3 and 4 present the two versions of the model, which make different The model has a continuum of voters with unit mass and two candidates, 1 and 2. ABSTRACT We consider the Hotelling–Downs model with n 3 office-seeking candidates and runoff voting. We show that Nash equilibria in pure strategies.

Control charts are graphical tools widely used to monitor manufacturing processes to quickly detect any change in a process that may result in a change in product quality. The statistic plotted on a control chart is based on samples of n ≥ 1 observations (rational subgroups) that may be taken at regular sampling intervals. However, there are numerous practical applications using individual obse...

The scientific literature is abundant regarding control charts in multivariate environments for numerical and mixed data; however, there are few publications qualitative data. Qualitative variables provide valuable information on processes various industrial, productive, technological, health contexts. Social no exception. There multiple nominal ordinal categorical used economics, psychology, l...

The monitoring of a multivariate process with the use of multivariate statistical process control MSPC charts has received considerable attention. However, in practice, the use of MSPC chart typically encounters a difficulty. This difficult involves which quality variable or which set of the quality variables is responsible for the generation of the signal. This study proposes a hybrid schemewh...

The inclusion of internal noise in model observers is a common method to allow for quantitative comparisons between human and model observer performance in visual detection tasks. In this article, we studied two different strategies for inserting internal noise into Hotelling model observers. In the first strategy, internal noise was added to the output of individual channels: (a) Independent n...

We propose a space–time Hotelling model that introduces a unit size of the vertical time axis in the classical Hotelling unit interval model. The proposed model allows explicit consideration of the probability that a consumer arrives at a retail store up to time t to purchase goods. The proposed model is useful in a variety of retailing problems. We briefly demonstrate an application of the pro...
