In ordinary regression, imposition of a lasso penalty makes continuous model selection straightforward. Lasso penalized regression is particularly advantageous when the number of predictors far exceed...
Let Y be a binary random variable and X a scalar. Let ^ be the
maximum likelihood estimate of the slope in a logistic regression of Y on
X with intercept. Further let x0 and x1 be the average of ...
