## BIVARIATE REGRESSION MODEL

10.1 INTRODUCTION

In Chapters 1 through 9 we studied statistical inference about the distribution of a single random variable on the basis of independent observations on the variable. Let {Xt}, t = 1, 2, . . . , T, be a sequence of independent random variables with the same distribution F. Thus far we have considered statistical inference about F based on the observed values {xt} of {X,}.

In Chapters 10, 12, and 13 we shall study statistical inference about the relationship among more than one random variable. In the present chapter we shall consider the relationship between two random variables, x and y...
