spacepy.seapy.sea_signif

spacepy.seapy.sea_signif(obj1, obj2, test='KS', show=True, xquan='Time Since Epoch', yquan='', xunits='', yunits='', epochline=True, usrlimy=[])[source]

Test for similarity between distributions at each lag in two 1-D SEAs

Parameters
obj1Sea

First instance for comparison

obj2Sea

Second instance for comparison

Other Parameters
test

(default = ‘KS’) Test to apply at each lag: KS is 2-smaple Kolmogorov-Smirnov; U is Mann-Whitney U-test

show

(default = True)

xquan

(default = ‘Time since epoch’ (None)) - x-axis label.

yquan

(default = ‘Time since epoch’ (None)) - y-axis label.

xunits

(default = None (None)) - x-axis units.

yunits

(default = None (None)) - y-axis units.

epochline

(default = True) - put vertical line at zero epoch.

usrlimy

(default = []) - override automatic y-limits on plot.

Examples

>>> obj1 = seapy.Sea(data1, times1, epochs1)
>>> obj2 = seapy.Sea(data2, times2, epochs2)
>>> obj1.sea(storedata=True)
>>> obj2.sea(storedata=True)
>>> seapy.sea_signif(obj1, obj2)
