Regression analysis comes with several applications in finance. For example, the statistical method is fundamental to theCapital Asset Pricing Model (CAPM). Essentially, the CAPM equation is a model that determ

This is why logistic regression has "regression" in its name, even though it is a classification model. The sigmoid function resembles an S-shaped curve in the image below. It takes the real numbered input values and converts them between 0 to 1 (by shrinking from both sides, i.e., ...

Bent-cable regression extends the popular piecewise linear (broken-stick) model, allowing for a smooth change region of any non-negative width. Here the authors consider autoregressive noise added to a bent-cable mean structure, with unknown regression and time series parameters. They develop ...
Regularization techniques are used to address overfitting and enhance model generalizability. Ridge and lasso regression are effective methods in machine learning, that introduce penalties on the magnitude of regression coefficients. However, their approaches and suitability differ depending on the specific ...
As the model complexity, which in the case of linear regression can be thought of as the number of predictors, increases, estimates' variance also increases, but the bias decreases. The unbiased OLS would place us on the right-hand side of the picture, which is far from optimal. That's ...

Creating a visualization from data is easy. In Tableau, it's only one click. What happens if you want to extract data from a visualization? A simple google search yields a few reverse engineering tools, yet they share the same malaise – they only work with single curve and require a lot...
