It does not really matter. Start to write your stat test and we will go over it. This is --highly-- important to have such tests.

I use class method for generic actions that are not to be performed per instance of data. But if I have multiple instances of data then instance methods make more sense. Some classes offer both instance and class methods doing the same process. So in the end its up to you there is no golden rule. For example you may have a class method that return the instance of the class which you can then use to trigger additional instance methods. Sky is the limit ;) On Tue, Mar 3, 2015 at 2:22 PM, Julien Delplanque <julien(a)tamere.eu> wrote: > On 03/03/15 13:11, Serge Stinckwich wrote: > > This is not really difficult to implement a khi2 or ks-test.

Re: [Pharo-users] SmaCC: First steps

by kilon alios

"Because this two productions define a list of stmt (possibly empty) and the AST generation code notices that, so it adds an s to statement and prepare that instance variable to be an OrderedCollection." yes but I find it a bit misleading because even when there is a single element it still going to create an OrderedCollection and still add "s" to the name of the variable. By they way I have been successful into implementing , with your help, a parser that parses python lists into pharo ordered collections. Python tuples and dictionaries are next. Have not implemented nesting types but that is very close too. Took me a lot of time to understand the syntax of SmaCC and moreover to be able to understand the grammar used for the PythonParser2. I decided not to change the grammar since it can do what I want as it is and augment any additional parsing with my own classes. Now I understand the meaning of tests, PyAtomNode and more importantly PyPowerNode. My overall experience with Smacc has been quite positive , the documentation is in a good state though I would like more practical examples especially on the matter of visitor. I love the Smacc syntax, its compact , readable and fairly easy to understand. I really like the design of the classes , make sense and are predictable. A final question is how up to date in the configuration loaded with configuration browser. The only thing I really missed from Smacc is a specialised to help me browse the huge python grammar. Scrolling around became very tedious .

I will do it soon but I'm still noob in smalltalk so I don't know where to implement this and how: class messages or object messages for example? Julien

This is not really difficult to implement a khi2 or ks-test. I'm doing that with my 1st year university student in Python. I will try if I found sone time in Pharo.

Doesn't look like there is what I'm looking for. Maybe I'll implement things I need if I have time but probably not a complete package for statistics. :) On 03/03/15 12:46, Alexandre Bergel wrote: > Hi Julien, > > Indeed, having a nice statistical package is missing in Pharo.

Hi Julien, there is no KS-tests in this package. This is also something I'm looking for :-) NumericalMethods package is now part of SciSmalltalk distribution: https://github.com/SergeStinckwich/SciSmalltalk Join us if you want to help build statistical tools in Pharo: http://groups.google.com/group/scismalltalk Regards Sent from my iPhone > On 3 mars 2015, at 11:52, Julien Delplanque <julien(a)tamere.eu> wrote: > > Wow lots of classes, I'll browse the package and tell you if that's what > I need :) > > Thanks. > >> On 03/03/15 11:46, Sebastian Tleye wrote: >> The only package that I know that has statistical tools is >> NumericalMethods, you can install it by going to tools->Configuraiton >> Browser->NumericalMethods. >> >> Check if it has what you need >> >> 2015-03-03 11:40 GMT+01:00 Julien Delplanque <julien(a)tamere.eu>: >> >>> Hi everyone, >>> >>> Does anyone know if there is a package that contains implementation of >>> statistics tests like Kolmogorov-Smirnov test, Khi-2 test, etc? >>> >>> I did fast research in Smalltalkhub but didn't found anything. >>> >>> Thanks in advance, >>> >>> Julien > >

Hi Julien, Indeed, having a nice statistical package is missing in Pharo. The numerical methods is a nice start. If things are missing, we should implement them.
