Missing geomagnetic flips suggest Earth’s past is dangerously incomplete
A team led by Japan’s National Institute of Polar Research has identified four time windows in the last 160 million years where Earth’s record of magnetic pole reversals appears to be missing entries.

The KDE procedure performs either univariate or bivariate kernel density estimation. Statistical density estimation involves approximating a hypothesized probability density function from observed ...
Nonparametric methods provide a flexible framework for estimating the probability density function of random variables without imposing a strict parametric model. By relying directly on observed data, ...
Gordon Lee et al introduce a data-driven and model-agnostic approach for computing conditional expectations. The new method combines classical techniques with machine learning methods, in particular ...
