Information that can be obtained by treating them as connected tests leads to the concept of discovery rates as well as to the Bayesian approach to hypothesis tests. It gives us great pleasure...
This is a brief overview of old and new developments in the theory and applications of stochastic approximation, an iterative scheme for statistical computation of certain kinds that has also found many engineering applications.
Benford’s Law or The First Digit Law as it is commonly known has been a fascination to many generations. This counter-intuitive law proposes that given a sequence of numbers (usually from a data set like length of rivers, height of mountains, populations of nations or any source of data from real life), the first digit is ‘1’ roughtly 30% of the time. Many mathematical sequences, such as Fibonacci...
