Hi guys is stdev a typical name for standardDeviation? Because I found it sad to have mean and stdev instead of mean and standardDeviation. Stef
In R, it is even shorter: https://stat.ethz.ch/R-manual/R-devel/library/stats/html/sd.html On Wed, Sep 28, 2016 at 7:50 PM, stepharo <stepharo@free.fr> wrote:

No this is my initials. I should have copyrighted them so may be we could have decent names. Le 28/9/16 à 21:26, phil@highoctane.be a écrit :

https://en.wikipedia.org/wiki/Standard_deviation says In statistics, the standard deviation (SD, also represented by the Greek letter sigma Ï or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values. But technically, our #stdev is only one of several variants, namely 'corrected sample standard deviation' [https://en.wikipedia.org/wiki/Standard_deviation#Corrected_sample_standard_d...] But you probably searched for it and did not find it since it was abbreviated ...

indeed and we have a funky abbreviation. I started an interesting book on DSP for dummies (engineers like me) and I would like to see what we can do. www.dspguide.com. I like that he does not focus on math for their correctness. Stef

stdev() or std() seems fairly typical. Doesn't mean we can't be different. One thing though is that the typical function is what newcomers would search on, which makes me consider it could be useful in Spotter to have a mapping from functions in other languages to Pharo methods. So a user would type stdev and the top hit would be standardDeviation.

Do not worry this is so complex to define that I will define my own in my own class for myself. Like that I will be able to use the names I want for my projects. You see in Rectangle we have a protocol named fmp and I was sad to see it. I would have preferred wtf Stef Le 29/9/16 à 02:52, Ben Coman a écrit :
