Answer:
For a given data set , the equation of the least squares regression line will always passes through the point (x,y)
Step-by-step explanation:
For a given data set , the equation of the least squares regression line will always passes through the point (x,y)
For :
- The least-squares regression line equation always passes through the point (x, y).
- The correlation "r" is the strength in relationship of a straight-line
- The square of the correlation,that is [tex]r^2[/tex] , is the fraction of the variation in the values of y that is given by the least -squares regression of y changes on x.
