Binary vs binomial distribution
WebRegression analysis on predicted outcomes that are binary variables is known as binary regression; when binary data is converted to count data and modeled as i.i.d. variables (so they have a binomial distribution), binomial regression can be used. The most common regression methods for binary data are logistic regression, probit regression, or related … Webyis essentially the binomial distribution with p= 0.5. The binomial distribution is usually used to model counts from a process with binary outcomes.
