Loss of fat below the skin in the cheeks, temples, chin, nose, and eye area may result in loosening skin, sunken eyes, and a skeletal appearance. Bone loss, mostly around the mouth and chin, may become evident after age 60 and cause puckering of the skin around the mouth.
Logistic regression allows one to predict a discrete outcome, such as group membership, from a set of variables that may be continuous, discrete, dichotomous, or a mix of any of these. Generally, the dependent or response variable is dichotomous, such as presence/absence or success/failure.
Test Run - Multi-Class Logistic Regression Classification. I consider logistic regression (LR) classification to be the âHello, world!â of machine learning (ML). In standard LR classification, the goal is to predict the value of some variable that can take on just one of two categorical values. For example, you might want to predict a personâs sex (male or female) based on their height and annual income.
