Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

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.
where K 0 (·) is a kernel function, is the bandwidth, n is the sample size, and x i is the i th observation. The KERNEL option provides three kernel functions (K 0): normal, quadratic, and triangular.

A kernel density curve may follow the shape of the distribution more closely. To construct a normal kernel density curve, one parameter is required: the bandwidth .The value of determines the degree ...
