What is E in covariance?
Answers
Step-by-step explanation:
yn. For two random variables x and y having means E{x} and E{y}, the covariance is defined as: Cov(x,y) = E{[ x - E(x) ][ y - E(y) ]} The covariance calculation begins with pairs of x and y, takes their differences from their mean values and multiplies these differences together.
Answer:
E(X) = μ is the expected value (the mean) of the random variable X and. E(Y) = ν is the expected value (the mean) of the random variable
