More on: Ed George at 70 Looks Better than I Looked at 45
I may have jumped the gun. I had assumed that the plan was to stay 2020 but going virtual. Maybe not. Maybe 2021 physical. We'll see. Keep checking the link.
Ed George at 70 Looks Better than I Looked at 45
Check him out: http://jh-cai.com/edgeorge70/. So unfair. Nevertheless I hope you will put my esteemed colleague's 70th birthday conference on your calendar and join the online festivities. His contributions are diverse and powerful. In many respects his work defines modern applied Bayesian analysis, as well as the modern interface of statistics and machine learning. I am immensely grateful for his leadership in research, in seminars, at dinners, and much more. His inspirational positivity runs through it all.

Big Data: Updated Historical Note and New BBC Podcast
On High-Dimensional, Non-Linear, Non-Gaussian Continuous-Time Likelihood Evaluation
Tired of trying to beat the particle filter into submission? Life has gotten a lot easier, at least for evaluating DSGE model likelihoods in continuous time. See the concluding section of the new and insightful survey, "Estimating DSGE Models: Recent Advances and Future Challenges" by Fernández-Villaverde and Guerrón-Quintana, which echoes section 5.1 of "Financial Frictions and the Wealth Distribution", by Fernández-Villaverde, Hurtado and Nuño (FVHN). FVHN show how to take advantage of the mathematical structure of a continuous-time DSGE model to evaluate its associated likelihood with almost no computational effort. In particular, solution of the Kolmogorov forward equation (the key to likelihood evaluation; see Lo (1987)) simply amounts to transposing and inverting a sparse matrix already computed when solving the model, which makes likelihood evaluation trivial and lightening-fast.

The HAC Emperor Has No Clothes: Part 3
A new paper by Dick Baillie, George Kapetanios and Kun Ho Kim, "Practical Approaches to Achieve Robust Inference in Time Series Regressions," brings all this into even sharper focus. Their beautiful Figure 1, reproduced below, says it all. The black dot is feasible GLS; the reds and blues are the standard nonparametric competitors. Presumably the paper will be posted soon. A related much earlier paper is here.

Density Forecasts and Density Realizations
Check out the interesting new paper below. Of course I am a fan of predictive densities (e.g., GDP fan charts). Usually I compare them to the "realization" (e.g., "published GDP"). But of course, as the authors emphasize, the realization is just a point estimate of true GDP, whereas in reality true GDP is itself uncertain and has its own density, which can be estimated (maybe...) from revisions. Very interesting. I wonder, for example, how predictive density assessments based on the probability integral transform (e.g., here) would need to be modified to account for uncertainty in the measured realization.
By: Galvao, Ana Beatriz (University of Warwick); Mitchell, James (University of Warwick) Abstract: GDP is measured with error. But data uncertainty is rarely communicated quantitatively in real-time. An exception are the fan charts for historical GDP growth published by the Bank of England. To assess how well understood data uncertainty is, we first evaluate the accuracy of the historical fan charts and compare them with models of past revisions data. Secondly, to gauge perceptions of GDP data uncertainty across a wider set of experts, we conduct a new online survey. Our results call for greater communication of data uncertainties, to anchor dispersed expectations of data uncertainty. But they suggest that transitory data uncertainties can be adequately quantified, even without judgement, using past revisions data. Keywords: data revisions; fan charts; expectations survey; backcasts; density forecast calibration JEL: C53 E32 Date: 2020 URL: http://d.repec.org/n?u=RePEc:wrk:wrkemf:35&r=ets

Carlo Bianchi RIP
Very sad to report that Carlo Bianchi, legendary organizer and host of the Bertinoro econometrics summer school (formally the CIDE Summer School of Econometrics) passed away today. His was an absolutely unique and endearing personage.
Whether or not you knew him, check out the testimonials at his retirement a few years ago:
