Linear Regression Quiz question 10
Q.A point for the slope of least squares regression line for all pairs in the population is
A.the slope of the regression line for the pairs in the sample.
Expl.
plz refer to defination of least square regression
Given a collection of pairs (x,y) of numbers (in which not all the x-values are the same), there is a line yˆ=βˆ1x+βˆ0 that best fits the data in the sense of minimizing the sum of the squared errors. It is called the “least squares regression line”. Its slope βˆ1 and y-intercept βˆ0 are computed using the formulas
βˆ1=SSxy/SSxx and βˆ0=y−βˆ1x
