#71 Factorial moment for poisson - 2 proofs
E(X(x-1)) is a 2nd factorial moment. Finding the factorial moment for rv~ poisson proved 2 ways - using the probability generating function of a poisson; directly from expectation of a function of a random variable

73-cumulant-generating-function-method
It's easier to work with the cumulant generating function cgf than the moment generating function in cases where it's easier to differentiate the cgf than the mgf. The first derivative of the cgf is the mean, the second derivative of the cdf is the variance of the random variable.

INTRO
introduction-to-the-cobweb-model-in-3
Pictures used to introduce the cobweb model. Don't worry - I don't do any algebra (although that doesnt mean I don't write down any equations!). Supplement to stuff we did in class. If it's going to convince you to watch this video, let's say I cover more here than I did in class on this topic.
What is the cobweb model?
How does the cobweb model work?
Can you show me a graph of how prices and quantity reach equilibrium over time in a cobweb model?
Does the cobweb model always get me to the market equilibrium price and quantity?
What are the equations for a cobweb model?
What conditions ensure the market equilibrium is stable for the cobweb model with linear supply and demand sets?
What happens when the conditions for market to be stable doesn't hold for the cobweb model?

DEPEN
dependent-variable-in-regression-is
I fitted a regression where Y was skewed,
but the residuals came out normal. How can this be?
Isn't it an assumption that the Y must be normally distributed
for the residuals to be normal too?
