Just wanted to share this development journey with you trying to build a template. I wanted to create a WordPress connector for DataShopTalk so that I could download all the articles and get a good idea of the content of the blog. Connecting directly to the MySQL database was not really ideal, I wanted to setup an API from WordPress so that a data function could connect to it.
QQ Plots are a standard visualization that compares the distribution of your data under study to the normal distribution. Since most statistical tests assume normality, the QQ Plot is an important diagnostic visualization during any analysis of uni-variate or multi-variate studies. We had a previous post that made a QQ Plot using custom expressions, and in this post we will show how to do it in TERR.
PCA (Principal Component Analysis) is a core data science technique for not only understanding colinearity of independent variables in a dataset, but can provide a reduced dimensional model by rotating your high-D data into lower dimensions. Here’s some quick info on getting PCA in Spotfire. If you want more info on PCA, of course check out Wikipedia.
Have you ever come across problems and errors while running the TERR scripts in Spotfire Data Functions which you didn’t have while running the same code as an R script outside Spotfire? There is a way to troubleshoot this issue by debugging your TERR code outside of Spotfire, i.e., in RStudio. Generally speaking, you need to enable your RStudio to run the TERRengine instead of R. Then, you want to be able to access your TERR Data Function Input Parameters from RStudio so that you can run and debug your TERR script there. How to do all that? It’s not that complicted. Please follow the steps below.
