GeoPandas – a detailed example

Dear World, Please send me more geographical data to plot so I can keep on using GeoPandas... Love from Sho't Left I can't believe how much fun this library is! So my goal was to find a way to map assessment ratings by region, showing the overall result for the region, as well as the... Continue Reading →

Which districts are my cities located in?

GeoPandas gets more and more exciting as the day wears on :). I've just discovered how ridiculously easy it is to take a set of cities and relate them to their corresponding districts, states or provinces and then plot the outcomes. Fanfare for... the marvellous GeoPandas spatial join! Here's a quick how-to guide to setting... Continue Reading →

GeoPandas Basics

Today's assignment - learn how GeoPandas can help me with data visualizations. Having fallen in love with Pandas this really did seem like the next logical step, and once you understand the principles behind it - which are actually quite nicely documented, then things flow quite logically. This is just the basics of course, but... Continue Reading →

Data mapping challenge

For the past month or so I've been working away at something that in hindsight looks deceptively simple - but nonetheless taught me loads of new techniques along the way: I wanted to plot data on a map in such a way that it would reflect ratings by province, taking into account the number of...

Multivariate regression

So: with linear regression (aka simple linear regression) we have one feature which we are using to predict a dependent value (for example number of rooms as a predictor of house price). With multivariate regression (aka multiple linear regression) we simply have multiple features which could be used to predict that dependent value (for example... Continue Reading →

Polynomial regression

Polynomial regression is a considered a special case of linear regression where higher order powers (x2, x3, etc.) of an independent variable are included. It's appropriate where your data may best be fitted to some sort of curve rather than a simple straight line. The polynomial module of numpy is easily used to explore fitting the best...

Yes I can API!

I have a "real" assignment (for work as opposed to study) to do some data visualizations using maps. It's been a journey of over a week to get to the place where I'm ready to start, and the journey has had some educational detours along the way that I thought I'd share. Naturally, because I'm...
