Note that interaction terms are likely necessary; ex: font color and background color
exploration v exploitation - CORRECT ANSWER-more information v immediate value -- with
regards to DOE
multi armed bandit approach - CORRECT ANSWER-testing k alternatives & starting with no
information; run test and update information about probabilities of each being the best, assign
new test Exploration, but since more likely to pick the best one, also exploitation
memoryless property - CORRECT ANSWER-it doesn't matter what happened in the past, all that
matters is where we are now (exponential and poisson)
balking - CORRECT ANSWER-person thinks the wait is too long and leaves without completing
transaction (checking out, talking to customer service rep on the phone, etc)
Bernoulli Distribution - CORRECT ANSWER-discrete distribution having two possible outcomes in
which ("success") occurs with probability p and ("failure") occurs with probability (1-p); similar
to flipping a coin but not constrained to 50/50
, Binomial Distribution - CORRECT ANSWER-Probability of getting x successes out of n
independent identically distributed Bernoulli(p) trials
Geometric Distribution - CORRECT ANSWER-Probability of having x Bernoulli(p) failures until
first success (or, x Bernoulli(1-p) successes until first failure)
Poisson Distribution - CORRECT ANSWER-Probability distribution for the number of arrivals
during each time period
Exponential Distribution - CORRECT ANSWER-Complimentary to poisson, if arrivals is
possion(lambda), time between successive arrivals is exponential(lambda)
Weibull Distribution - CORRECT ANSWER-the amount of time it takes something to fail,
specifically time between failures
Q-Q plot - CORRECT ANSWER-visualizing whether two distributions of data are about the same
or whether one data set is distributed similarly to a probability distribution; general idea:
whatever variations in the data there might be & even if the number of data points in the two
sets is very different, two similar distributions should have about the same value at each
quantile
deterministic - CORRECT ANSWER-always same results, not modeled / simulated / etc for
variance
stochastic - CORRECT ANSWER-includes model / simulation of some randomness
continuous-time simulation - CORRECT ANSWER-changes happening continuously
Discrete event simulation - CORRECT ANSWER-changes happen at discrete time points
