Control Charts for Quantile Function Values

Autor: Frank B. Alt, Scott D. Grimshaw

Publikováno v: Journal of Quality Technology. 29:1-7

A control chart is proposed which monitors the conformance of a sample to an in-control distribution using the quantile or inverse cumulative distribution function. This method permits detecting changes in the distributional shape which may be undete

Controlling multiple stream processes with principal components

Autor: Douglas C. Montgomery, George C. Runger, Frank B. Alt

Publikováno v: International Journal of Production Research. 34:2991-2999

A model for the measurements from a multiple stream process is analysed as a special case of a multivariate control chart by principal components analysis. The principal components meet the objective of partitioning the control problem into statistic

Choosing principal components for multivariate statistical process control

Autor: George C. Ranger, Frank B. Alt

Publikováno v: Communications in Statistics - Theory and Methods. 25:909-922

Principal components are useful for multivariate process control. Typically, the principal component variables are often selected to summarize the variation in the process data. We provide an analysis to select the principal component variables to be

Contributors to a multivariate statistical process control chart signal

Autor: Frank B. Alt, George C. Runger, Douglas C. Montgomery

Publikováno v: Communications in Statistics - Theory and Methods. 25:2203-2213

A significant practical disadvantage of multivariate statistical process control is that it is difficult to determine which of the monitored variables is responsible for the out-of-control signal. While there have been several proposed techniques and

The approximation of the one-step ahead forecast error covariance for vector ARMA models

Autor: Frank B. Alt, Ken Hung

Publikováno v: International Journal of Forecasting. 10:59-64

A vector case parallel to that described by Ledolter and Abraham ( Technometrics , 23 (1981) 411-414) is extended for an approximation of one-step ahead forecast error covariance for vector ARMA models.

The market reaction to announced deep cuts in capital expenditures

Autor: Yang-Tzong Tsay, Lawrence A. Gordon, Frank B. Alt

Publikováno v: Managerial and Decision Economics. 14:1-14

The objective of the study reported in this paper was to examine the role of deep cuts in capital expenditures as a firm's strategy for becoming more efficient and, in turn, more competitive. Based on an empirical study, support is provided for the a
