/BBox [0 0 362.835 2.657] The Bernoulli and Binomial probability distribution models are often very good models of patterns of occurrence of binary (“yes/no”) events that are of interest in public health; eg - mortality, disease, and exposure. 1. 0000001394 00000 n
A binomial distribution can be seen as a sum of mutually independent Bernoulli random variables that take value 1 in … Note that, if the Binomial distribution has n=1 (only on trial is run), hence it turns to a simple Bernoulli distribution. (7) /Filter /FlateDecode We say that a collection of trials forms a collection of independent trials if any collection of corresponding events forms a collection of independent events. 0000003226 00000 n
