<p class="MsoNormal">Suppose one sequences a relevant part of a genome of a bunch of patients -- some who get die from COVID-19 and some that do not -- giving say 10 million columns of data and a few thousand rows per patient. Which minimal set of those columns
are predictive of death? A function that includes these selection functions, each with a cost, and an outcome column would be typical in a variable selection procedure.<o:p></o:p></p>

The Iverson Bracket is a powerful generalization of the well known Kronecker Delta, very useful for embedding logical conditions and truth values into your formulas #Notation #MathType <o:p></o:p></p>
