Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The joint probability distribution of the random variables X and Y is given below: ? (?, ?) = ???, 0 <? <2, 0 <? <?

0, other

a. Find the value of the constant. b. Calculate and interpret the covariance and correlation of the X and Y random variables. c. Calculate the expected value and variance of the random variable ? = 2? − 3? + 2.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
