The purpose of this article is to propose that we focus the teaching of the introductory statistics course not merely on the statistical tools to be studied, but on the scientific thinking that they engender. Students must be taught that science is based on the testing of theories and shown how...

This paper talks about geometric progression (GP) and the formula for the sum of its finite terms. The formula is modified to find the sum of infinite terms of a GP for r ∈ (-1,1). An equation is found by substituting i (iota) for r. Arguments are provided for supporting such a substitution....

A new measure of asymmetry in dependence is proposed which is based on taking the difference between the margin-free coskewness parameters of the underlying copula. The new measure and a related test are applied to both a hydrological and a financial market data sample and we show that both...

Missing data is a problem appearing ubiquitously across many fields and needs to be dealt with systematically. For multivariate time series data imputation can be a challenging problem. We consider the particular case of credit default swap time series, where missing data can pose a considerable...

Financial markets have experienced several negative sigma events in recent years; these eventsoccur with much more regularity than current risk models can predict. There is no guarantee thatthe training set's data generating process will be the same in the test set in finance. Mathematicalmodels...

Outlier detection refers to the identification of rare items that are deviant from the general data distribution. Existing approaches suffer from high computational complexity, low predictive capability, and limited interpretability. As a remedy, we present a novel outlier detection algorithm...
