Advanced Regression Models: Learn which regression technique to apply for what cases?

Each of the regression analysis below contains working code examples with brief use-case explanations covered for each of the regression types in the list below. Many of these code snippets are generic enough so you could use them as a base template to start and build up on for your analyses.

Please note that the information presented in these pages should not be construed as full and complete analysis, but rather as a template and a hand guide of available modelling options. You are advised to pursue independent and thorough research before arriving at conclusions.

Method Application case
Robust Regression Applicable in all cases where OLS regression can be used. Applies re-weighting to reduce outlier influence.
Logistic Regression Models binary variables.
Probit Logistic Regression Models binary variables.
Multinomial Logistic Regression Models categorical variables with more that 2 levels.
Ordinal Logistic / Probit Regression Models ordinal or rank variables.
Poisson Regression / Negative Binomial Regression Models count variables. Neg Binomial is used when there is over-dispersion.
Ridge Regression Address Multicollinearity ?
Beta Regression Model variables within (0, 1) range.
Dirichlet Regression Model compositional data
Loess Regression Smoothing Time series.
Isotonic Regression For approximation of data that can only increase (..typically cumulative data)
