The following step-by-step example shows how to create a statistical process control chart in Excel.
Still, having done that, I wouldn’t change C++ for anything else - it’s very expressive and feels “just right.A statistical process control chart is a type of chart that is used to visualize how a process changes over time and is used to determine whether or not a process remains in a state of control. The problem is that there is still a lot of resources/books/websites/code around using the bad coding practices, etc., which may give a bad (and wrong) impression and it takes some time/experience to get to the good stuff (so there is some truth behind steep-learning-curve argument).

I’ve found that most people who complain about C++ being “hard” often also think it’s an object-oriented programming language like Java where you have to wrap everything in classes (thankfully, it’s not) and/or have been exposed to pre-1998 C-with-classes style standard (which can lead to code that, admittedly, is quite ugly).

my research) I’ve chosen C++ and it’s proven excellent so far - very fast, quite portable (easy to share & exchange ideas), and actually pleasant to program. Ultimately though, for most of the “serious” task (incl. Also used JAVA and C# in academic setting, currently interested in learning Haskell or OCaml (just to get the feeling for purer FP).
Oh, yeah, there was SAS too, but the language is way too ugly (kinda tempted to try out commercial version of R, S-PLUS, which can handle very large data). My experience is kinda similar to John’s - I know and use Mathematica (like it for symbolic computation), MATLAB (simple / non-time-critical matrix manipulation tasks), R (trying out fancy statistics packages), had a short episodes with Ox (C-like syntax, specialized for econometrics) and STATA (for traditional statistics/econometrics models on small data). R, Excel, and the Windows clipboard (good tips in the comments).Comparison of data analysis packages from Brendan O’Connor.This is a very useful function to have, even more useful than the Gamma function itself for reasons explained here. I discovered along the way that Excel has a GAMMALN function to compute the logarithm of the Gamma function Γ(x). The functions are individually reasonable even though they do not fit together into a simple pattern.įor details, see my notes Probability distributions in Excel 2007.
On the other hand, the most commonly needed functions are available. Having an asymmetric API makes it harder to remember what is available and how to use it. I wanted to emphasize that certain functions are everywhere, not only in mathematical packages like Mathematica and R, but also in Python and even Excel.Įxcel’s set of functions is inconsistent, both in the functionality provided and in the names it uses. I was looking into the functions in Excel 2007 while preparing for a class I taught yesterday. But if you think of Excel as a spreadsheet for everybody that sometimes lets you do statistical tasks right there without having to open up a statistical package, you’ll be pleased. If you expect anything similar to a statistical package, you’ll be sorely disappointed. Depending on your expectations, you may have different reactions to the statistical function support in Excel.
