A set of three documents: An R refresher and a Shiny introduction, together with exercises.
Tag:Consortium Apps
Tutorial on Knowledge Space Theory
n-Neighbourhood
Illustrating neighbourhoods in knowledge structures.
Reliability
How would your house look like if the carpenter building the windows is not fully reliable?
Animated Learning Paths v4
This app illustrates the concept of learning paths in a knowledge structure. It is an extension of an app from the TquanT project.
Modeling the 2018 PISA Dataset based on PCA and Clustering
A series of interactive tutorials introducing principle component analysis, clustering, linear modelling and cross-validation for large datasets.
QQplot
This Shiny app is meant to let you play around with a few different distributions (Normal, Skew Normal, Cauchy, Skew Cauchy), and check what the effect of different variables (scale, location and shape) on their qq-plot is.
The qq-plots are all a comparison with a default normal distribution (mean=0, sd=1). There is a large slider you can use to track specific percentiles on all graphs. This Shiny app was made for teaching purposes.
Distributions
This app illustrates the effect of violations of assumptions for the F distribution. It is an update of a TquanT app.
Modeling PISA Data by Clusters
An illustration of statistical learning and visualisation techniques using real-world data (PISA).
Properties of Relations
This app allows you to define an arbitrary binary relation on a set of five items and shows you whether certain properties are fulfilled.
