Keen to hear your thoughts #epitwitter #PublicHealthTwitter & #MedTwitter

Very fortunate to have had the pleasure to work with this amazing team. As nations rely on model-based forecasting and nowcasting, the timing of this review of calibration of models to epidemiological data is perfect #PLOSCompBio: https://t.co/dXOof6gWW4

@ProfMattFox You've given me renewed motivation to finally submit my paper on the Stochastic Modeling of Unimportant Rate Functions.

@ProfMattFox Is the question not rather do you pay extra to get something to go along with your guacamole?

[Wim Delva @WimDelva]

Hi #epitwitter, if I could only check out one model for a local (national) COVID epidemic, for which the source code is available, which one would you point me to and why? PS I'm looking for the best not the most noteworthy for other reasons.

[Wim Delva @WimDelva]

@ProfMattFox If it's perfect we shouldn't touch on the stringency level, assuming that co-determines its state of perfection?

As an associate professor, what’s a good number of PhD students to supervise at any point in time?

A proud day for all of us at @StellenboschUni !

@ProfMattFox Building on what @EpiCandice is suggesting: I don’t think we can define incidence for things we don’t consider “to be at risk of”. E.g. being male, being white. Also for “being 30-40 years old” incidence doesn’t make sense because we don’t think of it as a chance process.

And related to this: a term for the bias that arises when the fitted model reproduces the data well on average, but the simulated data has a variance that is too high or too low, compared to the variance of the empirical data? Apologies if I am asking a naive question here.

[Wim Delva @WimDelva]

Dear #epitwitter community, is there a well established term for a form of bias that arises from a model that is poorly fitted to the data in the sense that when the model is used to reproduce the data, it systematically produces values that are too high or too low?

[Wim Delva @WimDelva]

@ProfMattFox Ask students and colleagues who were not part of the paper if they can reproduce the analysis and results. Do whatever is in your power until their answer is yes.
