Any ideas on how to get the answers?
What do you guys have here?
Do you guys know how to find this?
Answered above :)
What is the correct answer? I don't really get the answers..
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 .
Yeah indeed, thanks!
Is this answer A) ? --> Sum of the last two periods divided by 2: (67,872 + 69,753) / 2 = 68,812.5
yes
does anybody know how to solve this?
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

I think it is E
Very Innovative New product so Bass Model for adoption of new products (note the delay as imitators start following early adopters)
Does someone know the answer for this one?
I would go to Compensatory decison rule . Both pretty much means the same things
What is the answers here?? :D Thanks

Nevermind got it :)
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 10350-10400= 50 11700-11675=25 11325-11300=25 12560-12560=0 (50+25+25+0)/4
Any ideas?
I would say December because the rest all has a negative coefficient and the intercept is positive (which has December as baseline)

I would also say B since you want everyone inside the cluster to be quite similar to each other so not heterogeneous.
Yes Within Cluster homogeneity and Across cluster heterogeneity
Does someone know how to solve this?
You take up until 451 as 1 cluster. Than the rest so 452 on its own is a cluster 453 =1 454 =1 455= 1 456=1 457=1 458=1 Which gives you 8 clusters in total
Perfect, I wasn't sure at all :)
