A brief introduction to Oswald : Object Oriented Software for theAnalysis of Longitudinal Data in SDavid
نویسنده
چکیده
Many general statistical packages now contain facilities for the analysis of longitudinal data. However, these facilities are typically limited in scope and do not exploit the particular character of longitudinal data in the way they handle basic operations such as data-entry, plotting and summarisation of results. Oswald (Smith & Diggle 1994) is a package of functions and data types for use with the S data analysis environment (Becker, Chambers & Wilks 1988). It was speciically designed for the manipulation, graphical display and analysis of longitudinal data, and implements many of the methods described in Diggle, Liang & Zeger (1994).

Declarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
