I am alone in thinking that this page needs considerable work? It covers only regression (and that only briefly). Here is a proposed reorganization:

Intro
Definition
Regression
1. Detection
2. Correction
3. Alternative methods of regression - link to quantile regression and robust regression
Univariate distribution
1. Measures of central tendency - with links to mean, median, trimmed mean
2. Measures of spread
3. Measures of skew
Bivariate distributions
Multivariate distributions (including curse of dimensionality)
Effects of outliers on other distributions

Additions to this before I start putting in a bunch of work are welcome (esp. expansion of item 7). -- PeterLFlomPhD (talk) 14:37, 7 August 2015 (UTC)[reply]

I agree that this page needs considerable work! Your outline looks pretty good to me (9 years later). I'm wondering if the applications (e.g. regression, univariate distribution, ...) should be grouped into a single section (applications?) and reordered in order of complexity (univariate, ...).

What originally piqued my interest in this article was getting confused between DFBETA and DFBETAS (the standardized version), which I'd like to add a clarification for. Statisfactions (talk) 17:27, 21 June 2024 (UTC)[reply]
