The normalized maximum likelihood (NML) is a recent penalized likelihood that has properties that justify defining the amount of discrimination information (DI) in the data supporting an alternative hypothesis over a null hypothesis as the logarithm of ...

Introducing shrinkage in heavy-tailed state space models to predict equity excess returns
We forecast S&P 500 excess returns using a flexible Bayesian econometric state space model with non-Gaussian features at several levels. More precisely, we control for overparameterization via novel global-local shrinkage priors on the state innovation ...

Efficient Bayesian Interference for Stochastic Volatility [PDF]
Bayesian inference for stochastic volatility models using MCMC methods highly depends on actual parameter values in terms of sampling efficiency. While draws from the posterior utilizing the standard centered parameterization break down when the ...

A Neural Stochastic Volatility Model
In this paper, we show that the recent integration of statistical models with deep recurrent neural networks provides a new way of formulating volatility (the degree of variation of time series) models that have been widely used in time series analysis ...

Forecasting Global Equity Indices Using Large Bayesian VARs [PDF]
This paper proposes a large Bayesian Vector Autoregressive (BVAR) model with common stochastic volatility to forecast global equity indices. Using a dataset consisting of monthly data on global stock indices the BVAR model inherently incorporates co ...

Estimating Functions and Equations: An Essay on Historical Developments with Applications to Econometrics [PDF]
The idea of using estimating functions goes a long way back, at least to Karl Pearson's introduction to the method of moments in 1894. It is now a very active area of research in the statistics literature. One aim of this chapter is to provide an account

An Ancillarity Paradox Which Appears in Multiple Linear Regression
Consider a multiple regression in which \(Y_ i\), \(i=1,...,n\), are independent normal variables with variance \(\sigma^ 2\) and E \(Y_ i=\alpha +V'_ i\beta\) where \(V_ i\in {\mathbb{R}}^ r\) and \(\beta \in {\mathbb{R}}^ r\). Let \({\hat \alpha}\) be the usual least squares estimator of \(\alpha\).
