Ordering factorial experiments

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2023
Abstract In many practical experiments, both the level combinations of factors and the addition orders will affect the responses. However, virtually no construction methods have been provided for such experimental designs. This paper focuses on such experiments, introduces a new type of design called the ordering factorial design, and ...

The experience factory

Proceedings of the 19th international conference on Software engineering - ICSE '97, 1997
This course presents the fundamental concepts behind software process and product improvement using measurement and evaluation in an Experience Factory Organization. It will provide a set of examples associated with understanding the software engineering process, product, and environment, improving it over time and packaging experience in the form of ...

Analysis of Factorial Survival Experiments

Biometrics, 1994
Several new methodological issues that arise within two-way factorial designs for survival experiments are discussed within the framework of asymptotic theory for the proportional hazards model with two binary treatment covariates. These issues include: the proper formulation of null hypotheses and alternatives, the choice among log-rank and adjusted ...

The Experience Factory

2014
Writing software is not like producing cars: its production process has a high degree of variability. To gain insights on how to improve a software development process, an approach is needed that systematically collects, organizes, and reuses experience.

Design Keys for Factorial Experiments

Applied Statistics, 1978
This paper describes the use of design keys in (a) identifying treatment effects with particular plot contrasts in factorial experiments and (b) constructing the designs. The method covers a wide variety of block structures. It is available for both symmetrical and asymmetrical designs.

Fractional Factorial Experiments

2017
When there are numerous treatment factors to be examined but a limited budget, it may only be possible to observe a small proportion of the treatment combinations. Some main-effect and interaction contrasts cannot then be distinguished and are said to be aliased.

Factorial Experiments with Time Trends

Technometrics, 1988
Time trends may affect the results of experiments that are conducted sequentially. A simple, yet powerful, way to model such an experiment is to represent the trend by an autoregressive integrated moving average time series model. I show how such models can be used to jointly estimate factorial and time-order effects and how they can be used as a ...
