Consider the problem from Lecture 4, “Search, Sampling and
Independence.” Assume that the distribution of prices from which
the consumer draws is (i) discrete and (ii) Uniformly distributed
with N possible stores/prices from which to draw.
(a) If the consumer is lost in the mall and doesn’t remember the
last store he visited (i.e. the last price he drew) and so cannot
avoid the possibility of returning to the same store, are
successive price draws dependent or independent?
(b) If the consumer is lost in the mall and does remember the last
store he visited (i.e. the last price he drew) and so can avoid the
possibility of returning to the same store, are successive price
draws dependent or independent?
Answer:
(a) If the consumer is lost in the mall and doesn’t remember the last store he visited (i.e. the last price he drew) and so cannot avoid the possibility of returning to the same store, are successive price draws dependent or independent?
Answer:
Consumer is lost in the mall and he doesn't remember the last stage he visited.Therefore, the successive draws will be dependent,since flake is still probability that he can visit he same store, and this is the all other probability
On uniform distribution
p(X=x) =1/N
(b) If the consumer is lost in the mall and does remember the last store he visited (i.e. the last price he drew) and so can avoid the possibility of returning to the same store, are successive price draws dependent or independent?
Answer:
If he does remember the last store he visited then he
will avoid to visit at this store,success price draw will be
independent of visiting the store.
