A single dose of psilocybin, a psychedelic that acutely causes distortions of space–time
perception and ego dissolution, produces rapid and persistent therapeutic effects in human …

This paper reviews the recent developments in the field of the variance‐ratio (VR) tests of
the random walk and martingale hypothesis. In particular, we present the conventional …

The wild bootstrap was originally developed for regression models with heteroskedasticity of
unknown form. Over the past 30 years, it has been extended to models estimated by …

Many empirical projects are well suited to incorporating a linear difference-in-differences
research design. While estimation is straightforward, reliable inference can be a challenge …

We study inference based on cluster-robust variance estimators for regression models with
clustered errors, focusing on the wild cluster bootstrap. We state conditions under which …

Bias-corrected approximate 100 (1-α)% pointwise and simultaneous confidence and
prediction intervals for least squares support vector machines are proposed. A simple way of …

We estimate time-varying income and price elasticities for energy demand for a 26-country,
middle-income balanced panel that spans 1996–2014. To do so, we employ a recently …

In this article I develop a wild bootstrap procedure for cluster-robust inference in linear
quantile regression models. I show that the bootstrap leads to asymptotically valid inference …

Cluster‐robust inference is increasingly common in empirical research. With few clusters,
inference is often conducted using the wild cluster bootstrap. With conventional bootstrap …

The relationship between the acute effects of psychedelics and their persisting
neurobiological and psychological effects is poorly understood. Here, we tracked brain …
