Hi all,
I am trying to understand the following question,
Customers were surveyed to assess their intent to purchase a product. An analyst divided the customers into groups defined by the company's pre-assigned market segments and tested for difference in the customers' average intent to purchase.
The following is the output from the GLM procedure:
source DF Sum of square Mean Square F value Pr>F
Model 7 15716.87902 2245.268 64.98 <.0001
Error 146 5044.56 34.5518
Corrected- 153 20761.44481
total
What percentage of customers' intent to purchase is explained by market segment?
Can someone explain this?
Thanks
Hint: Look up the definition of R-Square in a Statistics textbook.
Thanks for the hint...
R-sq= 1- SS error/SS total = 1 - 5044.5657/20761.4448 =0.76= 76%
15716.87902 / 20761.44481=0.757
