This work proposes a means for interconnecting optimal sample statistics with parameters of the process output distribution irrespective of the specific way in which these parameters change during transition to the out-of-control state (jumps, trends, cycles, etc). The approach, based on...

This paper examines team performance in the NBA over the last five decades. It was motivated by two previous observational studies, one of which studied the winning percentages of professional baseball teams over time, while the other examined individual player performance in the NBA. These...

The Gibbs distribution is often used to model micro-textures. This includes a definition of a neighbourhood system. If a micro-texture contains a large-scale variation, the neighbourhood system will be large, which implies many parameters in the corresponding Gibbs distribution. The estimation...

Given a set of n elements or observations that form a continuous variable, it is required to divide their distribution into k homogenous groups where k 2, and the purpose is to minimize the within-groups variance. This paper investigates procedures for such a division and shows how to find the...

In this paper, it is proposed to modify autoregressive fractionally integrated moving average (ARFIMA) processes by introducing an additional parameter to comply with the criticism of Hauser et al . (1999) that ARFIMA processes are not appropriate for the estimation of persistence, because of...

This paper presents a system of skip-lot sampling inspection plans designated as SkSP-3 based on the principle of a continuous sampling plan of type CSP-2. Expressions for performance measures such as Operating Characteristic function and ASN function are derived by the Markov chain approach....

The influence of observations on the parameter estimates for the simple structural errors-in-variables model with no equation error is investigated using the local influence method. Residuals themselves are not sufficient for detecting outliers. The likelihood displacement approach is useful for...

Two left-truncated survival data sets are collected in one-way factorial designs to examine the quality of products. We cannot specify our survival function completely, and only know that the tail has a power functional form of its argument. Thus, our problem is a left-truncated one with...

Well-formed polynomials contain the marginal terms of all terms; for example, they contain both x 1 and x 2 if x 1 x 2 is present. Such models have a goodness of fit that is invariant to linear transformations of the x variables. Recently, selection procedures have been proposed which may not...

This paper shows that when series are fractionally integrated, but unit root tests wrongly indicate that they are I(1), Johansen likelihood ratio (LR) tests tend to find too much spurious cointegration, while the Engle-Granger test presents a more robust performance. This result holds...
