Figure 5.3 Joint CDF for $X$ and $Y$ in Example 5.2 @ Graham Kemp. We also need \(E\left(XY\right)\), where: $$ \begin{align*} E\left(XY\right)&=\int\int{xy\ f\left(x,y\right)\ dydx}\\ &=\frac{2}{3}\int_{0}^{1}\int_{0}^{1}xy\left(2x+y\right)dxdy\\ &=\frac{2}{3}\int_{0}^{1}\int_{0}^{1}\left(2x^2y+xy^2\right)dxdy\\ &=\frac{2}{3}\int_{0}^{1}\left[\frac{2x^3y}{3}+\frac{x^2y^2}{2}|_0^1\right]dy\\ &=\frac{2}{3}\int_{0}^{1}{\left[\frac{2y}{3}+\frac{y^2}{2}\right]dy=\frac{2}{3}\left[\frac{2y^2}{6}+\frac{y^3}{6}\right]_0^1}\\ &=\frac{2}{3}\left(\frac{1}{3}+\frac{1}{6}\right)=\frac{1}{3} \end{align*} $$. Using this fact and Theorem 5.1.1, we have The correlation coefficient, usually written as \(Corr(X,Y)\) or \(\rho(X,Y)\), of two random variables \(X\) and \)Y is defined as: $$ Corr\left(X,Y\right)=\rho\left(X,Y\right)=\frac{Cov(X,Y)}{\sqrt{Var\left(X\right)Var\left(Y\right)}}=\frac{Cov(X,Y)}{\sigma_X\sigma_Y} $$. For $P(X_1 = - 1, P(X_2 = 1),$ the value is $1/2.$ How? Problem The number of cars being repaired at a small repair shop has the following PMF: \begin{equation} \nonumber P_N(n) = \left\{ \begin{array}{l l} \frac{1}{8} & \quad \text{for } n=0\\ \frac{1}{8} & \quad \text{for } n=1\\ \frac{1}{4} & \quad \text{for } n=2\\ \frac{1}{2} & \quad \text{for } n=3\\ 0 & \quad \text{otherwise} \end{array} \right. Joint probability mass function - forming a table. & \quad \\ Using the table generated while creating the PMF one can calculate the value of \(F_X(x)\) by summing all associated probabilities for possible values \(\leq x\). for all pairs \((x,y)\). \end{align} The joint PMF is represented by a table, where the number in each square (x,y) gives the value of pX,Y (x,y). \end{align}. Consider again the discrete random variables we defined in Example 5.1.1 with joint pmf given in Table 1. We know that: $$ \begin{align*} Var\left(X\right)&=E\left(X^2\right)-\left[E\left(X\right)\right]^2\\ &=\left[0^2\times0.4+1^2\times0.3+2^2\times0.3\right]-{0.9}^2\\ &=0.69 \end{align*} $$, $$ \begin{align*} Var\left(Y\right)&=E\left(Y^2\right)-\left[E\left(Y\right)\right]^2 \\ &=\left[1^2\times0.2+2^2\times0.4+3^2\times0.4\right]-{2.2}^2\\ &=0.56 \end{align*} $$, $$ \begin{align*} Corr\left(X,Y\right)&=\frac{cov\left(X,Y\right)}{\sqrt{var\left(X\right)var\left(Y\right)}}\\ &=\frac{0.02}{\sqrt{0.69\times0.56}}\approx0.03 \end{align*} $$. /a joint.
