Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.An explanation of logistic regression can begin with an explanation of the standard logistic function. The logistic function is a sigmoid function, which takes any real input , and outputs a value between zero and one. [2] For the logit, this is interpreted as taking input log-odds and having output probability.Humans use logarithms in many ways in everyday life, from the music one hears on the radio to keeping the water in a swimming pool clean. They are important in measuring the magnitude of earthquakes, radioactive decay and population growth.$\begingroup$ The natural log is also useful in a semi-log time series regression since the estimated coefficients can be interpreted as continuously compounded growth rates. $\endgroup$ – Jason B. Mar 27, 2012 at 18:20. ... I think that the natural logarithm is used because the exponential is often used when doing interest/growth calculation.(QUAD): Quadratic regression calculation.
