Hello fellow Data Science-Centralists!I wrote a post on my LinkedIn about why you should NEVER run a Logistic Regression. (Unless you really have to).The main thrust is:There is no theoretical reason why a least squares estimator can't work on a 0/1.There are very very narrow theoretical reasons that you want to run a logistic, and unless you fall into those categories it's not worth the time.The run time of a logistic can be up to 100x longer than an OLS model. If you are doing v-fold…See More

- The run time of a logistic can be up to…
