Intro to Linear Alg & Models,

Logistic Regression (binary response)

\[ \Pr(y) \sim \binom{n}{y}\theta^y(1-\theta)^{n-y} \] \[ \Pr(y=1)=\theta=\text{logit}^{-1}(\beta_0+\beta_1x_1+\beta_2x_2+...+\beta_7x_7) \]

  • Prerequisite: Ease going from quantile function to CDF, and back.
  • Difference: binomial variable, y, =1 and Pr(Y=1)
  • Difference: p(y=m | x) conditional class probability vs p(y | x), where m repsents a ‘class’, given x
  • Model y vs model log-odds (y)
  • Reason for modeling mean
  • Transformations of RV
