Variability Statistics (stats)

Functions

get_MAD(flux)	Get the median absolute deviation of an array of fluxes
get_sigmaG(flux)	Compute a rank-based estimate of the standard deviation
get_range(flux, bottom_percentile, ...)
get_skewness(flux)	Calculate the skewness of an array of fluxes
von_neumann_ratio(flux)	Calculate the (inverted) Von Neumann Ratio for an array of fluxes
J_stetson(time, mag, mag_err[, pair_threshold])	Calculate the J Stetson statistic as a measure of variability
periodogram(time, flux, flux_err, frequencies)	Generate a bootstrapped Lomb-Scargle periodogram and various associated statistics
longest_contiguous_chunk(times[, ...])	Create a mask for the largest contiguous chunk of observations
autocorr(time, flux[, largest_gap_allowed, plot])	Calculate the autocorrelation function for an array of fluxes
