We summarize eleven months of pro-bono work on statistical modeling and analysis of Covid-19 topics. For each of the papers and tutorials included here we provide a one-paragraph summary and commentary, including methods used, results, and possible public health applications, as well as the ResearchGate url to access them. Section 1 is an Introduction. In Section 2 we describe the web page...
An important issue in classification problems is the comparison of classifiers predictive performance, commonly measured as proportion of correct classifications and often referred to as accuracy or similarity measure.
This paper suggests a two-step fixed-sequence approach in order to identify the best performing classifiers among those selected as suitable for the problem at hand. At the...
