Linear vs. Non-linear Logistic Regression
Answer: Non-linear in probability, linear in log-odds.
Explanation: Logistic regression models log-odds linearly, but outcome probabilities non-linearly.
MSE and Gradient Descent Updates
- MSE Formula:
MSE = (1/n) * sum((yi - y_hat_i)^2) - Gradient Descent Update:
theta_new = theta_old - alpha * grad(MSE) - Explanation: Minimizes average squared error, updates parameters to reduce MSE.
BIC for GMM
- BIC Formula:
BIC = ln(n)*k - 2*ln(L_hat) - Explanation: Penalizes model
