This video follows from where we left off in Part 1 in this series on the details of Logistic Regression. This time we’re going to talk about how the squiggly line is optimized to best fit the data.

NOTE: In statistics, machine learning and most programming languages, the default base for the log() function is 'e'. In other words, when I write, "log()", I mean "natural log()", or "ln()". Thus, the log to the base 'e' of 2.717 = 1.

This video discusses the interpretation of a logistic regression’s coefficients and, more specifically, the slope of the independent variables when all other variables are held at their means. We also show evidence of the non-linear relationship between the independent variables and the dependent variable.

When you do logistic regression you have to make sense of the coefficients. These are based on the log(odds) and log(odds ratio), but, to be honest, the easiest way to make sense of these are through examples. In this StatQuest, I walk you though two Logistic Regression Examples, step-by-step, and show you exactly how the coefficients are derived and how to interpret them.

NOTE: In statistics, machine learning and most programming languages, the default base for the log() function is ‘e’. In other words, when I write, “log()”, I mean “natural log()”, or “ln()”. Thus, the log to the base ‘e’ of 2.717 = 1.

ALSO NOTE: Starting at 15:21, the left hand side of the equation should be “log(odds Obesity)” instead of “size”.
