360-2008: Convergence Failures in Logistic Regression

Convergence Failures in Logistic Regression Paul D. Allison, University of Pennsylvania, Philadelphia, PA ABSTRACT A frequent problem in estimating logistic regression models is a failure of the likelihood maximization algorithm to converge. In most cases, this failure is a consequence of data patterns known as complete or quasi-complete

Logistic Regression I The Newton-Raphson step is βnew = βold +(XTWX)−1XT(y −p) = (XTWX)−1XTW(Xβold +W−1(y −p)) = (XTWX)−1XTWz , where z , Xβold +W−1(y −p). I If z is viewed as a response and X is the input matrix, βnew is the solution to a weighted least square problem: βnew ←argmin β (z−Xβ)TW(z−Xβ) . I Recall that linear regression by least square is …

2 Given data like this, how can we learn to predict the prices of other houses in Portland, as a function of the size of their living areas? To establish notation for future use, we’ll use x(i) to denote the “input” variables (living area in this example), also called input features, and y(i) to denote the “output” or target variable that we are trying to predict
