A Visual Introduction to Machine Learning
This website explains very clearly, using good visualisations, how a Decision Tree algorithm can make useful predictions about how different attributes of a case, such as project, relate to the presence or absence of an outcome of interest. Decision tree models are a good alternative to the use of QCA, in that the results are easily communicable and the learning curve is not so steep. See my blog “Rick on the Road” for a number of posts I have made on the use of Decision Trees, for more information
