Nonparametric regression

Nonparametric regression

Nonparametric regression is a category of regression analysis in which the predictor does not take a predetermined form but is constructed according to information derived from the data. That is, no parametric form is assumed for the relationship between predictors and dependent variable. Nonparametric regression requires larger sample sizes than regression based on parametric models because the data must supply the model structure as well as the model estimates. (Wikipedia).

IntroLinearRegression.1.Intro

There is a written typo at 8:03 in this video. I write that the linearity assumption of a linear regression is "usually true," but that's not true. What I meant is what I actually said in the audio, which is that the assumption is usually not true. This video is brought to you by the Quan

Parametric and nonparametric tests

Parametric tests are most commonly used in healthcare research. They include tests such as Student's t-test and ANOVA. There is, however a rich set of non-parametric tests that are much more appropriate to use in certain circumstances.
