Sometimes the quality of a process is best expressed by a relationship between response
variables and explanatory variables. Checking over the time the stability of such functional …

A large number of aviation equipment maintenance data exhibit seasonal behavior, such as
aircraft failure rate. Consequently, seasonal forecasting problems are of considerable …

A profile is a relationship between the response variable (s) and the independent variable
(s), which describes the quality of a process or product. The profile can be monitored by a …

Brief Abstract This article focuses on estimation of multivariate simple linear profiles. While
outliers may hamper the expected performance of the ordinary regression estimators, this …

It is well known that performance of control scheme in phase II of statistical process control
depends on the estimators utilized in phase I. Sometimes, outliers may be present in the …

Although the Klobuchar model is widely used in single-frequency GPS receivers, it cannot
effectively correct the ionospheric delay. The Klobuchar model sets the night ionospheric …

In many topical applications, the product's quality can be well described in terms of statistical
regression relationships between one or more response and a set of explanatory variables …

Sometimes the relationship between dependent and explanatory variable (s) known as
profile is monitored. Simple linear profiles among the other types of profiles have been more …

Some quality characteristics are well defined when treated as response variables and are
related to some independent variables. This relationship is called a profile. Parametric …

In order to monitor some qualitative characteristics, it is necessary to examine the
relationship between a binary response variable and one or more descriptive variables. This …
