With these it helps You would hope that the estimated odds ratio is close to the realised proportions like this. You are estimating the probability pr(Y=1|X=x) ; the probability of a transaction given age rage and gender. With categorical predictors like this an intuitive estimator would be the proportions of outcomes in the data. Logistic regression becomes more interesting when the predictors are continuous variables, and you'd like to predict the probability of an outcome for some value of the predictor that you haven't observed. In these cases LR lets you map an unbounded linear function of your predictor onto a probability which must by definition be bounded between 0 and 1.
Support maximum screen aspect ratio without hard-coded ratio?
I wish this help you David's answer is correct if we want to support high aspect ratio screens on API < 24 (before Nougat). Going forward, however, the documentation says that android:resizeableActivity is true by default for API 24 and above. That means the app is automatically free-form in future (correct me if I am wrong). Considering that Galaxy S8 already ships with Nougat out of the box, I'd say there is no need to worry if your app is OK with free-form style. EDIT: If your targetSdkVersion is < 24 then you should use David's solution because free-form will not automatically kick in for phones OS with Nougat (or higher) installed.
