Traditionally, the success of Information Systems (IS) has been studied in the context of large organisations with a focus on systems that have been developed inhouse. Most businesses, however, are small and medium enterprises (SMEs), and they have increasingly adopted packaged application software. To evaluate their success we examined two research variables, namely user practices and design f...

Electroencepholography (EEG) and functional magnetic resonance imaging (fMRI) are two ways of recording brain activity; the former provides good time resolution but poor spatial resolution, while converse is true for latter. Recently, deep neural network models have been developed that can synthesize fMRI activity from EEG signals, vice versa. Because these generative simulate data, they make i...

Criteria for evaluating mathematical software packages and the results of a recent comparison of such packages are briefly reviewed. A benchmark problem that was developed based on the results of this comparison is presented. This problem can be used in various courses, representing various levels of knowledge in chemical process analysis, mathematical modeling and numerical methods where the s...

Most research on the utilization of standardized application software packages in large companies is focussed on introducing a certain package for entire processes or even the entire company. A mix of existing, mostly individual applications and selected modules of different standardized application packages, however, may be superior in certain situations. A cost-based model for information sys...

This paper addresses the evaluation of nonlinear methods in econometric software, taking GARCH procedures as a case study. In particular, it analyzes seven widely used packages, utilizing a recently developed benchmark. Four of the packages are found to be unsuitable, in most cases because the developer either does not specifically indicate which of the many possible GARCH models is being estim...

Software selection research has so far mainly focused on corporations and often assumed a rational evaluation of selection criteria. Research on consumers’ software selection is still scarce. However, findings from outside IS indicate that consumers’ software selection decisions might be biased by the choice alternatives among which software is selected. In an experiment, this study investigate...

Software installation provides an attractive entry vector for malware: since installations are performed with administrator privileges, malware can easily get the enhanced level of access needed to install backdoors, spyware, rootkits, or “bot” software, and to hide these installations from users. Previous research has been focused mainly on securing the execution phase of untrusted software, w...

This paper describes how to fit an additive Poisson model using standard software. It is illustrated with SAS code, but can be similarly used for other software packages.

Network meta-analysis (NMA)--a statistical technique that allows comparison of multiple treatments in the same meta-analysis simultaneously--has become increasingly popular in the medical literature in recent years. The statistical methodology underpinning this technique and software tools for implementing the methods are evolving. Both commercial and freely available statistical software packa...
