Welcome to WikiProject Statistics

Shortcuts

Some Wikipedians have formed this collaboration resource and group, whose aim is:

To improve Wikipedia's coverage of statistics and the organization of information and articles on this topic.

This page and its subpages contain their suggestions and various resources; it is hoped that this project will help to focus the efforts of other Wikipedians interested in the topic. If you would like to help, please join the project, inquire on the talk page and see the to do lists below.

This WikiProject covers articles related to statistics, including the history of statistics and biographies of statisticians. Articles within its scope include those in:

List of statistics topics
Category:Statistics and its sub-categories
Category:Statisticians and its sub-categories

An expandable tree view of subcategories of Category:Statistics is available at CategoryTree->Statistics.

As of 27 February 2021, there are 4,300 articles within the scope of WikiProject Statistics, of which 3 are featured and 19 are good articles. This makes up 0.07% of the articles on Wikipedia, 0.03% of all featured articles and lists, and 0.06% of all good articles. Including non-article pages, such as talk pages, redirects, categories, et cetera, there are 10,516 pages in the project.

A ranking of articles on statistical topics by recent page views is at Wikipedia:WikiProject_Statistics/Popular_pages.

The list of statistics topics is being extended to include existing articles not previously listed and any new or unlisted statistics-related articles should be added. The list contains over 2750 items, including some redirects (18 February 2013: was 2642 on 17 October 2011; 2233 on 29 July 2009; 1731 on 31 December 2008; and 945 on 22 May 2008). The list is not at present very sophisticated and this project could undertake general improvements given that lists are far more versatile than categories. Look at lists of mathematics topics for examples.

Some priority articles that the project hopes to make progress with are those in:

Category:Statistics stubs (313 articles)
Category:Statistics articles needing expert attention (54 articles)

Guidelines

Here are general guidelines for different types of articles in the project.

Consider adding one of these navigational boxes to the end of the article:

{{Statistics}} (example: Statistical hypothesis testing)
{{Least squares and regression analysis}} (example: Nonlinear regression)
{{Experimental design}} (example: Randomized block design)
{{Medical research studies}} (example: Randomized controlled trial)
{{Statistics journals}} (example: The American Statistician)
{{ProbDistributions}} (example: Binomial distribution)
{{Theory of probability distributions}} (example: Probability mass function)

Tag the discussion page with

{{WPStatistics|importance= | class=}}

and (if there is substantial mathematics content)

{{maths rating|field=probability and statistics | importance= | class=}}

using appropriate values for the class and importance parameters as described here.

General statistics articles

Use one or more sub-category of Category:Statistics
Tag stubs with {{statistics-stub}}

Probability distributions

Suggestions regarding the structure of articles about probability distributions are here
Include either of these infoboxes (feel free to leave some parameters blank):

{{Infobox probability distribution}} (e.g., Negative binomial distribution)
{{Infobox probability distribution 2}} (e.g., Geometric distribution)

Add an appropriate sub-category of Category:Probability distributions
Tag stubs with {{probability-stub}}

Biographies of statisticians

Include {{infobox scientist}} with all known information.
Add Category:Statisticians or one of its sub-categories
Make sure you follow the policy on Biographies of living persons
Add {{WPBiography}} to the article's discussion page (include "|living=yes" to the template for living persons)
Tag stubs with {{statistician-stub}}, {{UK-statistician-stub}} or {{US-statistician-stub}}

Open tasks

Article-related tasks

Here are some tasks awaiting attention:

Article requests : See requested articles in statistics, and in econometrics
Cleanup : Articles in WikiProject Statistics are regularly scanned automatically for cleanup templates. A list of statistics articles that need cleanup is here. You can help by reviewing the list and correcting any deficiencies.
Expand :
- Outline of statistics
- Outline of regression analysis
- Multivariate regression model needs detailed formulae for multivariate case
- Eigenpoll
- Directional statistics to include measures of dispersion for circular data
- Conjoint analysis improve statement problem to be solved (more maths?)
- Training set and Test set could be both merged and expanded.
- Overfitting could tie in test sets, the effects of high model complexity and curse of dimensionality as well as how adding noise sometimes alleviates the problem.
- Ancestral graph
- Spatial descriptive statistics which has essentially no content
- Likelihood function to remove bias towards Bayesian-only context
- mixed model spun out of redirect to multilevel model, but needs expansion
- Labour Force Survey needs expanding, including to improve geographic coverage
- Various Tsallis Pages, documented on Talk:Tsallis distribution#Tsallis Pages
- Joint probability distribution needs some examples, better examples, perhaps an explanation of uses and relationships with other concepts in statistics
- Bayesian linear regression alternative priors, advanced regression models, marginal densities, prior and posterior predictive density
- Monte Carlo sampling: Application to Approximate Bayesian Inference needs more explanation
- Approximate Bayesian Computation
- Cohen's h
Merge :
- Financial modeling and Modeling and analysis of financial markets
- Monte Carlo methods in finance and Monte Carlo methods for option pricing
- Variogram (which is redirected from semivariogram) and Semivariance
- Linear predictor function into Linear model
Split :
- Parameter into separate articles accessible from disambig pages
- Effect size into separate articles for each metric
Stubs :
Verify :
- Sampling distribution case of sampling from a finite population?
Other :
- Attend to
  - Category:Statistics articles needing expert attention (54 articles)
  - Category:Probability articles needing expert attention (3 articles)
- Redirects to convert to articles, or otherwise:
  - Influence function (statistics) — currently redirects to Robust statistic
  - hazard function
  - Time-series regression presently redirects to Time-series
  - Ridge regression presently redirects to Tikhonov regularization
  - Regression splines presently redirects to Smoothing splines
  - Fisher's protected LSD presently redirects to Post hoc analysis
  - Hill estimator presently redirects to Heavy-tailed distribution
  - Weibull chart presently redirects to Weibull distribution
- Groups of articles with substantial overlap:
  - Truncation (statistics) and Truncated distribution
  - Multiple testing correction and Multiple comparisons : need to separate multiple testing from “finding the best”
  - Efficiency (statistics) and efficient estimator
  - Variance and standard deviation

New articles

An automatically generated list of new articles is available here, based on these rules.

Please feel free to list here any new statistics-related articles that you create or come across (newer articles at the top, please) and also add them to list of statistics topics.

Bayesian hierarchical modeling 12 May 2014
Foundations of statistics 2 Sept 2013 major expansion from stub

Any new articles that have an interesting or unusual fact in them, are at least over 1,000 characters, do not have any dispute templates on them, and cite their sources, should be suggested for the Did you know? box on the Wikipedia Main Page.

New templates and categories

Please add new categories to this list as well as here.

Article assessment

Statistics WikiProject

The assessment is done in a distributed fashion through parameters in the {{WikiProject Statistics}} project banner; this causes the articles to be placed in the appropriate sub-categories of Category:Statistics articles by quality and Category:Statistics articles by importance.

Currently 5,270 pages have been tagged with the {{WikiProject Statistics}} template. Of these, 50 (1%) have not been assessed for quality and 330 (6%) have not been assessed for importance.

A log of recent changes in assessment is available here.
