Logitic **regression** is a nonlinear **regression** model used when the dependent variable (outcome) is binary (0 or 1). The binary value 1 is typically used to **indicate** that the event (or outcome desired) occured, whereas 0 is typically used to **indicate** the event did not occur. I got a question about ranking **regression** coefficients for a Lasso model for example. 1. I scaled my data X and Y (subtracted the mean of each variable, and divided with the standard deviation). 2. I obtained the **regression** coefficients, some are zero (non-important variables), and for the rest I get values, some are 0.2, 1, 2, 3.

The **Linear Regression** is a smoothing **functions** that works by preforming linear least squares **regression** over a moving window. It then uses the linear model to predict the value for the current bar. It takes one parameter, the period n. Larger values for n will have a greater smoothing effect on the input data but will also create more lag.
