When you implement Bayesian lasso regression in MATLAB®, be aware of several differences between the Statistics and Machine Learning Toolbox™ function lasso and the Econometrics Toolbox™ object lassoblm and its associated functions. lassoblm is part of an object framework, whereas lasso is ...
This MATLAB function creates a Bayesian linear regression model object composed of the input number of predictors, an intercept, and a diffuse, joint prior distribution for β and σ2.
This MATLAB function creates a Bayesian linear regression model object composed of the input number of predictors, an intercept, and a diffuse, joint prior distribution for β and σ2.
Create a diffuse prior model for the linear regression parameters. Specify the number of predictors p and the names of the regression coefficients. Get p = 3; PriorMdl = bayeslm(p,'ModelType','diffuse','VarNames',["IPI" "E" "WR"]) PriorMdl = diffuseblm with properties: NumPredictors...
The Bayesian linear regression model object semiconjugateblm specifies that the conditional prior distribution of β|σ2 is multivariate Gaussian with mean μ and variance V, and the prior distribution of σ2 is inverse gamma with shape A and scale B.
This MATLAB function returns a random vector of regression coefficients (BetaSim) and a random disturbance variance (sigma2Sim) drawn from the Bayesian linear regression model Mdl of β and σ2.
