Homework Answers
Logistic regression uses regression to predict the outcome of a categorical dependant variable on the basis of predictor variables.
Another objective of logistic regression is to check if the probability of getting a particular value of the dependant variable is related to the independent variable.

(10%)Q3 (Logistic regression): We collected n 15 independent binary observations : i- 1, , 15) and their corresponding covariates {xi : і = 1, , 15). Assume the relationship between yi and zi (for i = 1, , 15) is Vi ~ Bernoulli(p.) and logit(Pi)-α+82i, where logit(t) = log ti. Please 1) write down the likelihood function L(a, B|x, y) of the logistic regression model; 2) derive the Newton method...
