python-math

A collection of snippets I use to do a little math. Nothing fancy.

The mission

Make a single basket for all the math functions I use to do journalism
and, as it expands, try to translate everything out of numpy so I don’t
have to deploy its entire module to my production server.

Contains functions that calculate:

• Decile rankings
• ELFI (Ethnolinguistic Fractionalization Index)
• Mean
• Mean center
• Median
• Ordinal rank
• Per capita rate
• Per square mile rate
• Percentage change
• Percentage
• Percentile
• Standard competition rank
• Standard deviation
• Standard deviation distance
• Standard deviation ellipses

Other utilities to:

• Get a random point
• Nudge identical points slightly apart

Dependencies

• django
• geodjango
• math
• psql ellipse() function
• random
