comment Finding distribution parameters of a gaussian mixture distribution
@ChenStatsYu -- Send me an email and I can send you the notebook. You can find my address in my profile.

comment Change default output font globally
+1. I had hoped for a deeper level solution, that might even retroactively reformat my old notebooks, but this does look like maybe the best workaround. Any idea why I can't reset these settings in Option Inspector?

comment Combining Gravity Turn and Orbit Models
The Drexel University Mathematica Forum might make a better place to post this question. As I remember, the forum would entertain (even celebrate) any question either about (1.) how to do things in Mathematica or (2.) any problem that someone uses Mathematica to solve. This forum has a narrower focus, but I think it would benefit from expanding it to include questions like this one.

An adaptive Laguerre smoothing technique may give you just what you need. See below...

A question: do you use this I[n_, pmt_, pv_, fv_] anywhere?

comment Time value of Money Functions combined
Mma restricts the use of "N", N[expr] gives the numerical value of expr. Also "I",I represents the imaginary unit Sqrt[-1]. You need to use other function names.

@belisarius - re: Titian take a look at this link from the Frick collection in NY. You can zoom around the painting and see lots of this kind of thing.

Checked with Bradley. He replied, "...totaly fine to post my contact information..."

@Mr.Wizard - I contacted Brad directly for permission after seeing your concern and will certainly take his guidance. Note, one can, with little effort, obtain this contact information from public sources.

comment Computing the Hurst exponent or fractal dimension of fractional Brownian motion
I think he uses R as Rescaled Range (The rescaled range is a statistical measure of the variability of a time series...) Rescaled Range. Also see: Hust Exponent. I think I've got a notebook on this I'll try to dig it out of my archive.

comment Plotting Semi-hollow spheres
This really had me puzzled. So many simple ways that Mathematica ought to let one do this but doesn't ;-( Great solution with broad application. +1

comment Mathematica policy for correctness of results
Anyone developing serious software that may risk "Millions" should probably design an appropriate level of user acceptance testing prior to rolling it into production. Then, the responsibility properly falls on the user.
