Maximum Likelihood in Logistic Regression I We have binary responses y 1 , . . . , y n and data on p explanatory variables x ij , i = 1 , . . . , n and j = 1 , . . . , p .
Maximum Likelihood in Logistic Regression I We have binary responses y 1 , . . . , y n and data on p explanatory variables x ij , i = 1 , . . . , n and j = 1 , . . . , p . I We assume that y 1 , . . . , y n are independent Bernoulli random variables with parameters p 1 , . . . , p n .
Maximum Likelihood in Logistic Regression I We have binary responses y 1 , . . . , y n and data on p explanatory variables x ij , i = 1 , . . . , n and j = 1 , . . . , p . I We assume that y 1 , . . . , y n are independent Bernoulli random variables with parameters p 1 , . . . , p n . I We model the relationship between the response and explanatory variables by the formula log p i 1 - p i = β 0 + β 1 x i 1 + · · · + β p x ip . (1)
