June 2018 Newsletter

The main stories are "Diagnostics on Large Data Sets": a section from the updated GARCH course which explains the common problem of models on large data sets (1000's of observations) failing to pass standard diagnostics even when the model seems perfectly fine and "Toda-Yamamoto Causality Test: A Cautionary Tale" which explains how the often-used alternative to the Granger test is fundamentally flawed.


ARCH/GARCH and Volatility Models e-course updated

The ARCH/GARCH and Volatility Models e-course has been updated to a 2nd edition, which includes new and expanded treatment of many topics in GARCH modeling.


January 2018 Newsletter

The main stories are "Markov-Switching GARCH models", which is a summary of the section from the new edition of the Structural Breaks course; "How to Switch if you Must" describes the differences between three common types of regime-based behavior (structural break, threshold break and Markov switching) and how to choose which is appropriate; "Evaluation of GARCH Forecasts" looks at difficulties with using common forecast error statistics (like RMSE) in evaluating out-of-sample behavior of GARCH models.


Structural Breaks and Switching Models e-course updated

The Structural Breaks and Switching Models e-course has been updated to a 2nd edition, which includes new and expanded treatment of many topics in models with thresholds, breaks and Markov switching.


State-Space/DSGE e-course updated

The State-Space/DSGE e-course has been updated to a 2nd edition, which more than doubles the size of the original.


Enders, AETS, 4th edition

We've posted the worked examples for the 4th edition of Walter Enders' Applied Econometric Time Series, Wiley, 2015. This is an intermediate book on applied time series, and covers a broad range of applications from ARIMA models to GARCH models to cointegration. See the single book-browser for more.


VAR e-course updated

The VAR e-course has been updated to a 2nd edition, which adds over 50% more material.


Martin, Hurn and Harris, Econometric Modelling with Time Series

We've posted the worked examples from Martin, Hurn and Harris, Econometric Modelling with Time Series: Specification, Estimation and Testing, Cambridge University Press, 2013. This is a fairly advanced book which looks at time series analysis primarily by means of the likelihood principle. See the single book-browser for more.
