Simple linear regression (Python)

2012-05-12T13:36:55-07:00

Python recipe 578129 by Thomas Lehmann (decrease, increase, linear, math, percental, regression, simple). Revision 3.

What?

It's about forecasting.
It's about calculating a linear function.
Details I found: http://www.faes.de/Basis/Basis-Statistik/Basis-Statistik-Korrelation-Re/basis-statistik-korrelation-re.html (in german)

Also I don't know how the formula have been created the practical part was very easy to me. I have verified one example (see code) using Open Office Calc (I've learned: you can display the formula for the trend line as well as the coefficient of correlation - great).

Why?

In recipe 578111 I'm printing out current error rate for different training sessions in mental arithmetic.
Anyway I would like to be able to given information - approximately - about how many you have improved since you train yourself.

What has changed?

Revision2: Didn't compile with Jython 2.5.3b1 because of not supported exception syntax. Now it does work without exception.
Revision3: Test data row for failure not removed.

Simple Python Checker (Python)

2012-01-24T21:37:33-08:00

Python recipe 578023 by Thomas Lehmann (analyse, analyze, checker, code, python, simple). Revision 2.

Why this recipe?:

pylint is great but I does not support newer python versions.
I intended to write an own more simple parser recognizing that Python is doing the job for me and so I started to learn - a little - how to use AST.

In scope (for this recipe):

scanning a single python file displaying warnings and errors when breaking rules.
easy to maintain and easy extensible.
reporting messages in a way - when displayed in an editor - you can click on them to jump to the location for the relating message.
Lines of code means: without blanks (later: also without comments)

Out of scope (for this recipe):

For the recipe the folder/path support would break my limits. This include also the possible limits for this.
Checking for comments (SIngle line comments, block comments, checking for parameter documentation)

Future:

I'm thinking about putting this on a project base location (issue tracker, versioning, ...).
Of course same free license.
Providing a link here.
Checking for comments to handle further limits (LOC/COM, COM, checking for tags vs. parameters).
Allow to handle a path/folder with Python files (another statistic output)
