@Milan Ivica I really don't understand why you keep insisting in developing your own proprietary code (or use someone's code), when Mathematica already have all this GBM stuff internally... I think in my answer I've already shown exactly what you want for the 1-case and multiple-case paths...

comment Can I use GoogleMap or other GPS data in creation of the Graphs?
I think we have to be aware of this detail: "Use of the Distance Matrix API must relate to the display of information on a Google Map; for example, to determine origin-destination pairs that fall within a specific driving time from one another, before requesting and displaying those destinations on a map. Use of the service in an application that doesn't display a Google map is prohibited.". This information can be accessed here

comment Can I use GoogleMap or other GPS data in creation of the Graphs?
@Alex If you want to compute distances using Google Maps I think one approach is to decode the Google Directions API polylines and compute distances directly from it... I know it can be done in C# and Java... However I'm stil wondering how to do this with Mathematica.

@Alex So you actually don't need to create a graphic? You need to compute distances based on Google Maps/GPS? So I think it would be interesting to edit the question and put something more clear like "Can I use Google Maps or GPS data to compute road distances"?

@Milan Ivica I don't think you need to define a new BrownianMotion function once you can use GeometricBrownianMotionProcess from Mathematica... Try, for instance, example[trend_] := RandomFunction[ GeometricBrownianMotionProcess[trend, .4, 1], {0, 10, .01}]["Path"] and then use ListLinePlot[Table[example[trend],{trend,{0,.3,.5}}]]...

Could I assume the same for the Pearson correlation test?

comment Why is there no PositionFunction in Mathematica?
I can speak for myself, as I have several notebooks where I use Position. So, I believe Position is used more often than you think by the vast majority of users (not only unexperienced ones)...

comment Why is there no PositionFunction in Mathematica?
BTW, congrats for the 60K ! Is there any way to "suggest" this function in the next version of Mathematica?

comment AR(1) Process first term
I don't think the documentation is clear about removing the mean... the shift operator E in the Details uses 1 instead of an $a_0$-term. In the Applications part there is a single example (daily exchange rates of the euro to the dollar) where it removes the mean and then add it back for forecasting... I don't think an example is clear enough for defining the function...
