Abstract
The application is online and free-available. The core of the application is written in language R.
The R is a free-as-in-beer and free-as-in-speech programming language and environment for statistical computing and graphics and is widely used among statisticians, econometricians, or biologists - it ensures reliability of computations performed by the application. Code chunks written offline in R language were uploaded online using shiny package to a server dedicated to R calculations.
Shiny package is a library written also in R which provides an online framework for R scripts. The application is available at R server of the First Faculty of Medicine, http://shiny.statest.cz.
Application uses Czech as a language of choice since we aim on Czech-speaking researchers and students. The flowchart integrated into application helps to make correct statistical decisions depending on the type of inputted data and intended statistical hypothesis; its design arises both from common good practise and from author's experience in this field, too.
Statistical methods which are processed so far cover both parametric ones such as t-tests, F-tests or family of ANOVA and others; and non-parametric ones such as Wilcoxon tests, Kruskal-Wallis tests or Friedman ANOVA and others. These methods are directly linked with the flowchart leaf nodes.
