The gamma distribution is used to model non-negative data that has an inherent right skew, such as income.

Gamma Regression: The gamma distribution is used to model non-negative data that has an inherent right skew, such as income.

In many data generation processes for count data, it is possible that a lot of observations will have a count of zero.

The poisson distribution is specified by one parameter lambda that represents both the mean and variance of the distribution.

Poisson regression uses the following cost function:

Poisson regression is used where target variable is measured in counts.

The equivalent of the overall F-Test in logistic regression is Deviance.

Each ? is interpreted as the change in log odds of a success for a 1-unit increase in the corresponding predictor, holding all other variables constant.

Logistic regression relates the log odds to the weighted combination of predictors and coefficients
