Cardinality in math relies on the cardinal, or counting, numbers. Cardinality tells how many of something exist. In a set, cardinality tells how many elements are in a set.What Is a Set? A set is simply a collection of elements. For example, the man has a set of dishes. The set in...
Forum:General Math J What Is the Cardinality of Bloch Waves in Quantum Mechanics? According to the Bloch's theorem, the solutions of SE in a periodic potential may be written as superpositions of Bloch waves. But what kind of superpositions are these? There is the continuous wave vector param...

High-cardinality (nominal) categorical covariates are challenging in regression modeling, because they lead to high-dimensional models. For example, in generalized linear models (GLMs), categorical covariates can be implemented by dummy coding which results in high-dimensional regression parameters for hig...
