  3. Mixed logit - Wikipedia

    en.wikipedia.org/wiki/Mixed_logit

    Mixed logit is a fully general statistical model for examining discrete choices.It overcomes three important limitations of the standard logit model by allowing for random taste variation across choosers, unrestricted substitution patterns across choices, and correlation in unobserved factors over time. [1]

  4. Multilevel model - Wikipedia

    en.wikipedia.org/wiki/Multilevel_model

    Multilevel models are a subclass of hierarchical Bayesian models, which are general models with multiple levels of random variables and arbitrary relationships among the different variables. Multilevel analysis has been extended to include multilevel structural equation modeling , multilevel latent class modeling , and other more general models.

  5. Random effects model - Wikipedia

    en.wikipedia.org/wiki/Random_effects_model

    In econometrics, a random effects model, also called a variance components model, is a statistical model where the model parameters are random variables. It is a kind of hierarchical linear model , which assumes that the data being analysed are drawn from a hierarchy of different populations whose differences relate to that hierarchy.

  6. Mixed model - Wikipedia

    en.wikipedia.org/wiki/Mixed_model

    A mixed model, mixed-effects model or mixed error-component model is a statistical model containing both fixed effects and random effects. [ 1 ] [ 2 ] These models are useful in a wide variety of disciplines in the physical, biological and social sciences.

  7. Completely randomized design - Wikipedia

    en.wikipedia.org/wiki/Completely_randomized_design

    The model for the response is , = + + with Y i,j being any observation for which X 1 = i (i and j denote the level of the factor and the replication within the level of the factor, respectively) μ (or mu) is the general location parameter; T i is the effect of having treatment level i

  8. Ridge regression - Wikipedia

    en.wikipedia.org/wiki/Ridge_regression

    Ridge regression is a method of estimating the coefficients of multiple-regression models in scenarios where the independent variables are highly correlated. [1] It has been used in many fields including econometrics, chemistry, and engineering. [2]

  9. Isotonic regression - Wikipedia

    en.wikipedia.org/wiki/Isotonic_regression

    Isotonic regression is also used in probabilistic classification to calibrate the predicted probabilities of supervised machine learning models. [ 2 ] Isotonic regression for the simply ordered case with univariate x , y {\displaystyle x,y} has been applied to estimating continuous dose-response relationships in fields such as anesthesiology ...
