Origin and Use of the Laplace Distribution in Daily Sunspot Numbers
Patrick L. Noble, Michael S. Wheatland
Recently Pop ({\it Solar Phys.} {\bf 276}, 351, 2012) identified a Laplace (or double exponential) distribution in the number of days with a given absolute value in the change over…

A Bayesian Approach to Forecasting Solar Cycles Using a Fokker-Planck Equation
Patrick L. Noble, Michael S. Wheatland
A Bayesian method for forecasting solar cycles is presented. The approach combines a Fokker--Planck description of short--timescale (daily) fluctuations in sunspot number (\citeaut…

Modeling the Sunspot Number Distribution with a Fokker-Planck Equation
Patrick Noble, Mike Wheatland
Sunspot numbers exhibit large short-timescale (daily-monthly) variation in addition to longer timescale variation due to solar cycles. A formal statistical framework is presented f…
