What is Multivariate Testing? | Data Science in Minutes
In this tutorial, we will explain: how a multivariate test differs from an A/B Test, how to create and conduct a multivariate test, and what questions you should be asking of your test. Multivariate testing is a technique for testing a hypothesis in which multiple variables are modified.

Parametric and nonparametric tests
Parametric tests are most commonly used in healthcare research. They include tests such as Student's t-test and ANOVA. There is, however a rich set of non-parametric tests that are much more appropriate to use in certain circumstances.

Andreas H. Hamel: From set-valued quantiles to risk measures: a set optimization approach to...
Abstract : Some questions in mathematics are not answered for quite some time, but just sidestepped. One of those questions is the following: What is the quantile of a multi-dimensional random variable? The "sidestepping" in this case produced so-called depth functions and depth regions, a

[my xls is here https://trtl.bz/2I01sOF] The problem with the typical R-squared (aka, coefficient of variation) is that it can be artificially increased by simply adding more independent variables (aka, regressors). A higher R^2 does not necessarily imply that the model is a better fit. Th

Realized (ex post) alpha is the regression intercept. Study notes: 1. Active return is not alpha. Active return is just the portfolio's outperformance versus the benchmark, but outperformance is partially explained by beta exposures. 2. As with any regression, we cannot easily parse the t
