3.2.1 Cumulative Distribution FunctionThe PMF is one way to describe the distribution of a discrete random variable. As we will see later on, PMF cannot be defined for continuous random variables. The cumulative distribution function (CDF) of a random variable is another method to describe the ...

EMD decomposes a time series into a non-oscillatory trend and a sequence of oscillatory intrinsic mode functions (IMFs) that differ in their characteristic frequencies. It allows for both nonlinearity and nonstationarity and gives an intuitive and data-driven understanding of the underlying fluctuations...

Before we move to looking at the relationship between wins and population, it's useful to understand the distribution of wins alone. A few notes of interpretation: The number of wins is skewed and looks like a negative binomial distribution, which makes sense conceptually The "typical" value he...
