Statistical software for Engineers 2

[Timusop]

Hello all,

Can anyone recommend any free statistical analysis software (ideally for engineering). I really need something ASAP, I am looking at normal distributions of surface asperities.

I look forward to your input, thanks.

What kind of analysis, exactly? Lots of calculators do statistics, as does Excel. Or:

Thanks IRStuff,

It seems that the software is not compatible with the Windows 64bit OS. Is there any alternatives. I wanted to be able to plot statistical graphs, e.g. normal distribution, etc easily without having to type PDF formulas etc. Hope that makes sense.

Thanks again.

XLSTAT

has a 30-day free trial. It's an Excel plug-in,
works great for me.

Good on ya,

I haven't used it, but maybe R:

So, what's wrong with Excel? It's got a bunch of statistics functions built-in

I use MathCAD. Very similar to Excel except better formulae writing for documentation in addition to a calculator.

Thanks everyone, I ended up using Excel to do this task. I really appreciate your input.

While Mathcad wuold certainly be my SW of choice, its graphic capabilities haven't changed much since version 1. I tend to use MC for the calculations and the graph things in Excel.

Yes I agree, both Smath Studio and MathCAD can not match Excel in its graphing capabilities, but then again I don't think it's meant to. As always, we need more than one tool for the job. Thanks.

 

[IRstuff]

So, if you already had MC or even SMath, why didn't you use them?

I think MINITAB is awesome stats software!

I haven't used it, but maybe R:

I haven't had a need to sit down and learn it, but R seems quite powerful. R seems to have quite a loyal following, and there are plenty of examples and an active user base on the web.

For the little bit of sadistical... erm... statistical work that I have to do, Octave (or Matlab) has plenty of functionality.

Octave (and R) have the benefit of being free.
