Session 2, Reading 10: Probability distributions
This video continues a review of quantitative methods in the CFA. I'm dividing them to two parts, so this is Part One and the next video will be Part Two. In this video, we will look at common probability distributions. Specifically, we look at...
A previous video in this CFA playlist looked at classic measures of central tendency. This is also called the first moment of the distribution or the distributions the location where is the distribution centered. When we say that I think most of us think of the average or the mean, but we saw...
Statistics is broadly either descriptive (aka, exploratory data analysis, EDA) or inferential (e.g., making predictions or forecasts). There is generally only one defined population and descriptive measures of the population are called parameters (and denoted with Greek symbols; e.g., mu, µ, for...
The holding period return (HPR) is given by [P(t) + D - P(0)]/P(0). The HPR does not account for the time interval, so importantly it is annualized; for example, a 15.50% HPR over 5 years is much less impressive than over one month. The time-weighted return (TWR) chains HPR together and is given...
