WebThe raw data in this situation are a series of binary values, and each has a Bernoulli distribution with unknown parameter θ representing the probability of the event. There is no error term in the Bernoulli distribution, there's just an unknown probability. The logistic model is a probability model. Share Cite Improve this answer Follow WebA probability distribution is a mathematical description of the probabilities of events, subsets of the sample space. The sample space, often denoted by , is the set of all possible outcomes of a random phenomenon being observed; it may be any set: a set of real numbers, a set of vectors, a set of arbitrary non-numerical values, etc.

WebThe event is binary, so the outcome is either 0 or 1. We have collected a lot of data of the form { { r 1, A 1 }, { r 2, A 2 }, ⋯, { r n, A n } } where r i ∈ R and A i ∈ { 0, 1 }. For example: { { − 3, 0 }, { − 2, 1 }, { 2, 1 }, { 2, 1 }, { 1, 0 } } Can we somehow estimate the probability of A being 1 for a certain r.
