G Sometimes, people consider a simple linear regression model without the intercept term. Given data (x1, y1),(x2, y2), . . . ,(xn, yn), consider the following model yi = βxi + ?i , i = 1, . . . , n where we assume ?i ∼ N(0, σ2 ) and they are independent. (a) (10 pts) What is the distribution of yi? Write down the distribution and parameters. (by) (10 pts) Express the total square error as a function of β and find βˆ that minimizes the tot

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
