  2. Linear regression - Wikipedia

    en.wikipedia.org/wiki/Linear_regression

    The extension to multiple and/or vector-valued predictor variables (denoted with a capital X) is known as multiple linear regression, also known as multivariable linear regression (not to be confused with multivariate linear regression). [10] Multiple linear regression is a generalization of simple linear regression to the case of more than one ...

  3. Regression analysis - Wikipedia

    en.wikipedia.org/wiki/Regression_analysis

    All major statistical software packages perform least squares regression analysis and inference. Simple linear regression and multiple regression using least squares can be done in some spreadsheet applications and on some calculators. While many statistical software packages can perform various types of nonparametric and robust regression ...

  4. Commonality analysis - Wikipedia

    en.wikipedia.org/wiki/Commonality_analysis

    Commonality analysis is a statistical technique within multiple linear regression that decomposes a model's R 2 statistic (i.e., explained variance) by all independent variables on a dependent variable in a multiple linear regression model into commonality coefficients.

  5. Multilevel regression with poststratification - Wikipedia

    en.wikipedia.org/wiki/Multilevel_regression_with...

    The multilevel regression with poststratification model involves the following pair of steps: MRP step 1 (multilevel regression) : The multilevel regression model specifies a linear predictor for the mean μ Y {\displaystyle \mu _{Y}} , or the logit transform of the mean in the case of a binary outcome, in poststratification cell j ...

  6. General linear model - Wikipedia

    en.wikipedia.org/wiki/General_linear_model

    The general linear model incorporates a number of different statistical models: ANOVA, ANCOVA, MANOVA, MANCOVA, ordinary linear regression, t-test and F-test. The general linear model is a generalization of multiple linear regression to the case of more than one dependent variable.

  7. Partial correlation - Wikipedia

    en.wikipedia.org/wiki/Partial_correlation

    A simple way to compute the sample partial correlation for some data is to solve the two associated linear regression problems and calculate the correlation between the residuals. Let X and Y be random variables taking real values, and let Z be the n-dimensional vector-valued random variable.

  8. Multilevel model - Wikipedia

    en.wikipedia.org/wiki/Multilevel_model

    In other words, a simple linear regression model might, for example, predict that a given randomly sampled person in Seattle would have an average yearly income $10,000 higher than a similar person in Mobile, Alabama. However, it would also predict, for example, that a white person might have an average income $7,000 above a black person, and a ...

  9. Polynomial regression - Wikipedia

    en.wikipedia.org/wiki/Polynomial_regression

    Although polynomial regression fits a nonlinear model to the data, as a statistical estimation problem it is linear, in the sense that the regression function E(y | x) is linear in the unknown parameters that are estimated from the data. For this reason, polynomial regression is considered to be a special case of multiple linear regression. [1]
