Bayesian Model Selection in Social Research
Article
Article
Adrian E. Raftery · Sociological Methodology · 1995
It is argued that P-values and the tests based upon them give unsatisfactory results, especially in large samples. It is shown that, in regression, when there are many candidate independent variables, standard variable s...

Regression and time series model selection in small samples
Article
Article
Clifford M. Hurvich; Chih‐Ling Tsai · Biometrika · 1989
A bias correction to the Akaike information criterion, AIC, is derived for regression and autoregressive time series models. The correction is of particular use when the sample size is small, or when the number of fitted...

Likelihood Ratio Tests for Model Selection and Non-Nested Hypotheses
Article
Article
Quang Vuong · Econometrica · 1989
In this paper, we develop a classical approach to model selection. Using the Kullback-Leibler Information Criterion to measure the closeness of a model to the truth, we propose simple likelihood-ratio based statistics fo...

Regression Shrinkage and Selection Via the Lasso
Article
Article
Robert Tibshirani · Journal of the Royal Statistical Society Series B (Statistical Methodology) · 1996
SUMMARY We propose a new method for estimation in linear models. The ‘lasso’ minimizes the residual sum of squares subject to the sum of the absolute value of the coefficients being less than a constant. Because of t...
