Chap. 5: Joint Probability Distributions

Chap. 5: Joint Probability Distributions Probability modeling of several RV s We often study relationships among variables. Demand on a system = sum of demands from subscribers (D = S1 + S2 + . + Sn). Surface air temperature & atmospheric CO2. Stress & strain are related to material properties; random loads; etc. Notation: Sometimes we use X1 , X2 , ., Xn Sometimes we use X, Y, Z, etc. 1. Sec : Basics First, develop for 2 RV (X and Y). Two Main Cases I. Both RV are discrete II. Both RV are continuous I. (p. 185). Joint Probability Mass Function (pmf) of X and Y is defined for all pairs (x,y) by p( x, y ) P( X x and Y y ). P( X x, Y y ). 2. pmf must satisfy: p( x, y) 0 for all ( x, y). x y p( x, y) 1.

6 II. Both continuous (p. 186) A joint probability density function (pdf) of X and Y is a function f(x,y) such that • f(x,y) > 0 everywhere f and ³³ A P[( X, Y) A] f ( x, y)dxdy

www.asc.ohio-state.edu

Elasticity The price elasticity of demand measures the sensitivity of the quantity demanded to changes in the price. Demand is inelastic if it does not respond much to price changes, and elastic if demand changes a lot when the price changes. • Necessities tend to have inelastic demand.

regression uses the logit transformation to linearize the non-linear relationship between X and the probability of Y. It does this through the use of odds and logarithms. ... negative number. Odds cannot be less than zero, but all odds less than 1 yield natural logs that are negative…the floor is gone. Taking the natural log of the number 1 ...

Lecture 1: Stationary Time Series

www.asc.ohio-state.edu

It is clear that a white noise process is stationary. Note that white noise assumption is weaker than identically independent distributed assumption. To tell if a process is covariance stationary, we compute the unconditional first two moments, therefore, processes with conditional heteroskedasticity may still be stationary.

Recall that the density function of a univariate normal (or Gaussian) distribution is given by p(x;µ,σ2) = 1 √ 2πσ exp − 1 2σ2 (x−µ)2 . Here, the argument of the exponential function, − 1 2σ2(x−µ) 2, is a quadratic function of the variable x. Furthermore, the parabola points downwards, as the coefficient of the quadratic term ...

A function is a probability density on the interval I if the function is non-negative and in-tegrates to 1 over I. Therefore for any non-negative function f such that R I f(x)dx = C, the function p(x) = f(x)/C is a density on I; f is referred to as the unnormalized density

The density of states function describes the number of states that are available in a system and is essential for determining the carrier concentrations and energy distributions of carriers within a semiconductor. In semiconductors, the free motion of carriers is limited to two, one, and zero spatial dimensions.
