I think the answer is B.
A. doesn't make sense because the brand switching matrix doesn't show probability of buying one brand alone
C is incorrect because the probability is 0.5
D 0 percent doesn't mean they CANNOT buy it in the next COMING periods
E They have the chance to buy it, Not that they will buy it

Any clue for this one? My best guess is that we add up the numbers for each row:
T: (3+7)/2 = 5
E: (3+5)/2 = 4
F: (7+5)/2 = 6
Invert them as the scale is reversed and thus the answer would be the 3rd graph.
Any ideas on if this is correct?
I would say it is e, so the last one. If you check the table, you can see that fortune and time have the highest dissimilarity 7 that is why they should be far away from each other. Economist and fortune have a dissimilarity of 5, so they shouldn't be as close as economics and time which have a similarity of 3 .
its E. As the number of clusters is the number of grouped Xs (the grouos of X that are next to each other) so in the bottom row each X that is alone counts as a cluster each, and the 3 X together for Ivo and Ann make anther cluster. so 7 in total). hope that helps
you take the difference between the actual and predicted values (all in absolute values meaning you have no negative values) then you sum them up and divide by the number of periods
