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...

Polar bar chart challenge

A big thanks to ujubee.com for challenging me to create a polar bar chart last week - I hadn't done one of these before, but the matplotlib polar_bar_demo documentation was most excellent - and you can see from the test sample below that the results are very pretty! If you're interested in a bit more... Continue Reading →

My 1st Dashboard :)

  15 buildings, 35 aspects per building, each weighted according to importance, and then condensed into 6 key categories, with colour coding depending on how the results tumble out. What helped me get the final result? Pandas to import data from spreadsheet extract only the data I need manipulate it so we end up with... Continue Reading →

The joys of real world data... I received a file today with building floors: 1st, 2nd, 3rd, all the way to 22nd... Regular sorting quickly got me nowhere, with results that started 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 1st, 22nd, etc. This led to my discovery of the most marvellous natsort...
