8.LINEAR REGRESSIONS

ADDITIONAL PROBLEMS

1.y = -.6x+ 103.1

2.y = 1.006x - 1410.4

BLACKLINE MASTER 8.3

ACTIVITY 1

1.y=1.02x + 11.86

ACTIVITY 2

1.y=.03x + 41.858

2..0607

9.OTHER REGRESSIONS AND MODEL OF BEST FIT

ADDITIONAL PROBLEM

The best fitting regression model (excluding the cubic and quartic models because the addition of additional predictors will always increase r2) is the quadratic model of Y = -.07x2+ 9.26x –

240.52with a r2 value of .6254. The remaining models and corresponding r values were:

exponential	.4997
natural exponential .	4997
power	.4793
linear	.4788
natural log	.4601
base ten log	.4601
inverse	.4411
