7 steps for calculating predictor x in regression equation

1. calculate E(X) and E(Y)

2. calculate "actual minus expected" for each variable, for each observation

3. square "actual minus expected" JUST FOR X

4. DO NOT square "actual minus expected" for Y

5. instead, take (actual - expected of X) x (actually - expected for Y)

6. add up what you got for 3 and 5

7. take the ratio of the two (with XY on the top)

4

calculating intercept for regression equation

take the slope you calculating...

1. multiply it by your E(x)

2. subract that from your E(y)

5

how to interpret regression equation (use following example):

Y = 1.28 + .10443X

when the value of our X variable increases by 1, the value of our Y variable increases by .104

for every $10 increase in hourly income, the number of meals eaten out in a month increases by about 1
