Can someone please explain what is going on here?
I am using IDL 4.0 on a SUN Ultra-Sparc running Solaris 2.5.
IDL> ran_nums = randomn(seed, 1.e7)
IDL> print, moment( ran_nums )
-9.62740e-05 0.984964 -0.00155998 0.0514126
IDL> print, moment( ran_nums + 100. )
110.819 68.0284 -2.29521 0.120336
This problem goes away with N_elements = 1.e6.
What is it that I need to know to explain this behavior?
Thanks.
