Thanks for advertising. Validation / assessment of generalizability are tough topics, see also @f2harrell 's book and ncbi.nlm.nih.gov/pubmed/2598…

It has been claimed that there is no such thing as a validated prediction model. We provide empirical evidence for that claim in our new paper here onlinelibrary.wiley.com/doi/… with ao @Esteyerberg @DavidKlaveren see also @MaartenvSmeden @BenVanCalster @laure_wynants

New OA paper with Lu Tian and @robtibshirani. We show how to use the thousands of trials from the Cochrane database to improve the statistical inference for any given trial. We may expect gains that are roughly equivalent to doubling the sample size! onlinelibrary.wiley.com/doi/…

Evaluating a shrinkage estimator for the treatment effect in clinical trials

The main objective of most clinical trials is to estimate the effect of some treatment compared to a control condition. We define the signal-to-noise ratio (SNR) as the ratio of the true treatment...

Good to see the philosophical background to uncertainty highlighted. For decision making, Peirce wrote a brilliant 2 column Science paper in 1884, including Youden index and Net Benefit science.org/doi/10.1126/scie…

We sometimes communicate risk as “we expect that out of 100 patients like you 5 will get disease X, but how do we communicate uncertainty?what if we said we base this prediction in the model on34 patients like you” #ESMDM23

"The generalizability of [clinical predictive] algorithms often goes untested, leaving the community in the dark on their accuracy & safety when applied to a specific medical setting." This commentary aims to provide clarity on generalizability objectives. nature.com/articles/s41746-0…

Additive hazards model: ever wondered what to do about negative hazards and why the default method is ordinary least squares and not maximum likelihood? Then this will be of interest! @bds_lumc Maximum likelihood estimation in the additive hazards model onlinelibrary.wiley.com/doi/…

Maximum likelihood estimation in the additive hazards model

The additive hazards model specifies the effect of covariates on the hazard in an additive way, in contrast to the popular Cox model, in which it is multiplicative. As the non-parametric model,...
