SUMMARY GEIGER is a new software package, written in the R language, to describe evolutionary radiations. GEIGER can carry out simulations, parameter estimation and statistical hypothesis testing. Additionally, GEIGER's simulation algorithms can be used to analyze the statistical power of comparative approaches. AVAILABILITY This open source software is written entirely in the R language and ...

In this article, we present TripleR, an R package for the calculation of social relations analyses (Kenny, 1994) based on round-robin designs. The scope of existing software solutions is ported to R and enhanced with previously unimplemented methods of significance testing in single groups (Lashley & Bond, 1997) and handling of missing values. The package requires only minimal knowledge of R, a...

Consequently, to establish academic programs and to gain recognition as a profession, software engineering must have accreditation guidelines.

In order to evaluate the reliability of information system with hybrid structure, a logical structure based reliability evaluation model for information systems is proposed for assessing hardware and software reliability for information system, in which the hybrid structure is used to architecture the reliability model, and the reliability value is used to quantitatively describe the reliabilit...

This paper describes the architecture fo r the distributed CAPS system (DCAPS). The system accomplishes distributed software prototyping with legacy module reuse. Prototype System Description Language (PSDL), the prototyping language, is used to describe real-time software in the DCAPS system. PSDL specifies not only realtime constraints, but also the connection and interaction among software c...

Because speech recognition R&D is conducted in large part through the creation and modification of computer software, productivity depends heavily on software engineering issues , the ease of writing new software and reusing existing software. These issues are relevant not just to the work within a particular R&D group, but also to the exchange of technology among different groups. In particula...
