Since I mentioned kernels last week, I figured this would be a good time to go over the geographically weighted regression (GWR) procedure in SAGA. Once again, I don't have good example data I can post online for this topic, so you'll have to forgive the lack of pictures. GWR is an interesting method with… Continue reading Geographically Weighted Regression in SAGA
Today's vocab word can mean a lot of things in different contexts, but it almost always means the center or core. A kernel can refer to the edible interior of a nut or seed. In computer science, a kernel is part of an operating system. On Spatially Challenged, I'm usually referring to kernel in a… Continue reading Vocab Word: Kernel
Have you ever made a map or graph and been disappointed with the image quality or resolution? It happens to all of us, so today I'm sharing two quick tips for what to check the next time this happens. Low image resolution happens more frequently with large graphics, since some software programs have a default… Continue reading DPI and Image Quality
Last month I posted about how to read box plots, and today I'm sharing how you can make your own. I picked two online tools that don't require you to calculate the mean and quartiles yourself and shared a quick couple lines of code for the R users out there. Let's start with Desmos! Desmos… Continue reading Making Box Plots
Here on Spatially Challenged, I post things people ask me about. The bigger topics (SAGA GIS, data sources, Word tricks, etc.) get turned into series of how-to posts, and the smaller questions inspired a series of vocab posts. Today we're talking about the words Euclidean and Cartesian. Euclidean means "related to Euclid." Euclid was a… Continue reading Vocab Words: Euclidean and Cartesian
Just a brief post so that any subscribers see that the About Me page has been updated! I made a post earlier about my recent move to Wisconsin to do a PhD at UW-Madison, but just got a chance to update the static page. Thanks for reading!
Box and whisker plots are one of my favorite ways to visualize data, but they can be challenging to read if you haven't seen them before. Today I'm going to show a couple examples, and in the future I'll show you how to make your own! Firstly, box and whisker plots are also called boxplots.… Continue reading Box and Whisker Plots
