GSS Guided Statistics for Scientists

It can be intimidating to read across statistical text books, trying to find the correct statistical analysis for a study. And since statistics is such a large field, it is often difficult to understand when to use which analysis or test. We understand that scientists want to conduct appropriate statistics, but their focus is science and not statistics. Therefore, we developped GSS, a statistical software and support system, which helps scientists to quickly find and conduct the correct analyses. Nevertheless, GSS is a powerful software with professional capabilities, offering many options when needed.

Derived vs original data?

When presenting the findings of a study people often don’t show the original data that were measured, but they create so called ‘derived data’. Derived data can be: Percentages, rates, rtios, indices, etc.. For example, considering a data set on smoking behaviour, percentages could be used to describe the proportion of smokers in a sample…

GSS dose response analysis

Dose-response analyses

Overview Dose-response curves are use used to describe the relation of dose (e.g. of a pharmaceutical) and the resulting effect. To do this, dose response functions are fitted to measured data. These functions can then be used to calculate of important benchmarks such as the EC50 (dose leading to 50...
