  2. Bayesian multivariate linear regression - Wikipedia

    en.wikipedia.org/wiki/Bayesian_multivariate...

    The classical, frequentists linear least squares solution is to simply estimate the matrix of regression coefficients ^ using the Moore-Penrose pseudoinverse: ^ = (). To obtain the Bayesian solution, we need to specify the conditional likelihood and then find the appropriate conjugate prior.

  3. Regression analysis - Wikipedia

    en.wikipedia.org/wiki/Regression_analysis

    For example, a researcher is building a linear regression model using a dataset that contains 1000 patients (). If the researcher decides that five observations are needed to precisely define a straight line ( m {\displaystyle m} ), then the maximum number of independent variables ( n {\displaystyle n} ) the model can support is 4, because

  4. Frisch–Waugh–Lovell theorem - Wikipedia

    en.wikipedia.org/wiki/Frisch–Waugh–Lovell...

    Yule 1907 [8] also introduced the partial regression notation which is still in use today. The theorem, later associated with Frisch, Waugh, and Lovell, and Yule's partial regression notation, were included in chapter 10 of Yule's successful statistics textbook, first published in 1911. The book reached its tenth edition by 1932. [9]

  5. Multivariate statistics - Wikipedia

    en.wikipedia.org/wiki/Multivariate_statistics

    Certain types of problems involving multivariate data, for example simple linear regression and multiple regression, are not usually considered to be special cases of multivariate statistics because the analysis is dealt with by considering the (univariate) conditional distribution of a single outcome variable given the other variables.

  6. Multivariate adaptive regression spline - Wikipedia

    en.wikipedia.org/wiki/Multivariate_adaptive...

    In statistics, multivariate adaptive regression splines (MARS) is a form of regression analysis introduced by Jerome H. Friedman in 1991. [1] It is a non-parametric regression technique and can be seen as an extension of linear models that automatically models nonlinearities and interactions between variables.

  7. Linear least squares - Wikipedia

    en.wikipedia.org/wiki/Linear_least_squares

    Mathematically, linear least squares is the problem of approximately solving an overdetermined system of linear equations A x = b, where b is not an element of the column space of the matrix A. The approximate solution is realized as an exact solution to A x = b', where b' is the projection of b onto the column space of A. The best ...

  8. Total least squares - Wikipedia

    en.wikipedia.org/wiki/Total_least_squares

    It is a generalization of Deming regression and also of orthogonal regression, and can be applied to both linear and non-linear models. The total least squares approximation of the data is generically equivalent to the best, in the Frobenius norm , low-rank approximation of the data matrix.

  9. Multilevel regression with poststratification - Wikipedia

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

    The technique essentially involves using data from, for example, censuses relating to various types of people corresponding to different characteristics (e.g., age, race), in a first step to estimate the relationship between those types and individual preferences (i.e., multi-level regression of the dataset).
