This video is part of my series of videos on an introduction to econometrics. This is part of the math review.
- Circumcision Variance Steve Scott director of NOCIRC of Utah explains variations in circumcision that account for variations in ***ual (dis)function in men circumcised as infants. Why do/did you have foreskin? The foreskin occupies a prominent position on an important organ. The foreskins location and structure indicate that it is the most important sensory tissue of the penis. Its persistence over millions of years suggests that it has played a role in the propagation of the species. A well-integrated organ Structurally, the penis is highly integrated. The glans, foreskin and skin of the penile shaft function as a single unit, not as a collection of separate parts with entirely different functions. The functions of the glans and foreskin are similar, and overlapping, but come fully into their own at different times during intercourse. Simple sensations The outer surface of the foreskin is specialized to detect feather-light touch and other sensations, including painful ones. The infamous zipper injury is an extreme example of the sort of damage the outer skin was designed to detect and prevent, long before the zipper posed a threat to the uninitiated. Compared with the true (outer) skin of the foreskin, the glans is only feebly sensitive to light touch, pain, heat and cold. This is part of the reason we call the foreskin the primary sensory tissue of the penis. Without the foreskin, the end of the penis is numb to a host of sensations that tell the owner whether one of his most prized organs ...
- Basis risk (versus minimum variance hedge) Basis risk is the variance of the basis, where basis is the difference between spot and futures price. Or, here I've just replaced future (F) with (hedge ratio * Future). The minimum variance hedge ratio (h*) is then the hedge ratio (the special case of the hedge ratio) that happens to minimize the basis risk; and we can find that by taking the first derivative of basis risk (with respect to the hedge ratio). Spreadsheet is available at our website.

- Variance swap A variance swap can be used to hedge tail risk. One counterparty (Sally the trader, in this example) pays a forward (fixed) variance in exchange for a future, REALIZED variance. So she is "long volatility" and will profit if the realized variance is greater than expected. The advantage of a variance (or volatility) swap is the relatively pure bet on volatility; eg, it is not a directional bet on price and lacks some of the Greek exposures of (eg) an option. You can get the spreadsheet I wrote for this on our website!

Part 1 covers basic concepts, ie how to derive PV (Planned Value), EV (Earned Value) and AC Actual Cost. (These terms are also known as BCWS, BCWP and ACWP respectively.) Part 2 shows how to apply these items to calculate variances (SV - Schedule Variance, CV - Cost Variance, SPI - Schedule Performance Index, CPI - Cost Performance Index). Part 3 explains how Earned Value Management is used to forecast project performance by calculating EAC - Estimate at Completion, ETC - Estimate to Complete, VAC - Variance at Completion, and TCPI - To Complete Performance Index.

- RUU #18: Standard deviation, variance and averages In this clip, I wrap up my previous two clips by showing that more data will indeed give better reliability for a Bayesian test between two binomial models. I introduce the concept of standard deviation as a "characteristic width", and show how the variance (the square of the standard deviation or the expected square differences between expectancy and outcome) behaves for an average of repeatable independent trials. At the end I use Chebychev's inequality to show that the probability of getting an outcome outside a given number of standard deviations decreases with that number. I also show that for averages, increasing the number of measurements decreases the probability of getting outcomes outside a fixed range around the expectancy. Which means that I can get a given reliability on a Bayesian test between two binomial models with enough data. A PDF version of the slides can be found at the following address, for those interested in going through the algebra at their own leisure: folk.uio.no
