Regression Coefficient
While analysing regression in two related series, we calculate their regression coefficients also. There are two regression coefficients like two regression equations. Regression equation is that ratio which tells that with a changes of 1 in one series what will be an average changes in other series. In reality it is an algebraic measurement of the slope of regression line, means it decides the slope of regression line.

Consider the following linear regression model: a) What does y and x 1 , x 2 , . . . . x k represent? b) What does β o , β 1 , β 2 , . . . . β k represent?
Bernoulli's Theorem If a trial of an experiment can result in success with probability p and failure with probability q (i.e.1-p) the probability of exactly r success in n tri
There may be two values which occur with the same maximum frequency. The distribution is then called bimodal. In a bimodal distribution, the value of mode cannot be determined with
