Abstract

Objective: In this study, it is aimed to develop a new user-friendly web-based software to easily carry out Bayesian tests, which are becoming more and more common, instead of using the classical approach, which is generally preferred in analysis from statistical modeling.
Method: Shiny, an open-source R package, is used to develop the recommended web software. In the developed software, by selecting “the Specify Sample Number” tab, the number of samples presented as “Single”, “Two” options is selected, and analyzes are made by selecting the appropriate data set from the file upload menu.
Results: The data set “ulcer recurrence” was used to examine the way the developed web-based software works and to evaluate its output. To test whether there is a difference in age variable in terms of result variable, “Two Independent Sample Bayes Tests” were selected and analyzes were performed. According to the results obtained, statistically “little evidence for Ho” was found for the age variable in terms of the result variable. With the evidence obtained, it is said that no statistically significant difference was obtained for the dependent variable according to the independent variable.
Conclusion: The developed software is a new user-friendly web-based software that can be used to easily use Bayesian tests used as an alternative to the classical approach.
