Recall Bayes' Rule P(AIB) = P(A)P(B|A) PB) Suppose 1 in 100 birds is a duck. 1 in 10 birds walks and talks like a duck (for instance, some geese walk and talk like ducks despite not being ducks) 9 out of 10 ducks walk and talk like a duck (some ducks refuse to conform. Here I am saying that the bird walks and talks like a duck, given that the bird is a duck) The probability that a bird is...

To save on expenses, Rona and Jerry agreed to form a carpool for traveling to and from work. Rona prefers to use the somewhat longer but more consistent Queen City Avenue. Although Jerry prefers the quicker expressway, he agreed with Rona that they should take Queen City Avenue if the expressway has a traffic jam. The following payoff table provides the one-way time estimate in minutes for traveling to or from work: State of Nature Expressway Open Expressway Jammed Decision...

Background The notation P(AlB) is read as "the probability of A,
given B, has occurred." So the "" symbol is read as "given."
Formally, A and B are called events and P(AB) is a conditional
probability Bayes' rule is a very useful way of relating
conditional and unconditional probabilities. According to this
rule, for any two events A and B, we have: P(B) Let's use "T+" to
denote the event "the screening test concludes that the condition

Please answer 9.5 from Networks by Mark Newman
tion 9.3.3 for Internet data 9.5 The false positive rate B defined in Section 9.3.5 is the probability of erroneously observing an edge where none exists. Arguably a more useful measure, however, is the false discovery rate, which is the probability that an actual observed edge is itself a false positive, which is not the same thing. Suppose we measure a network once, producing an observed adjacency matrix O with elements Oij....
