Exploratory Regression 'Shiny' App

Constructs a 'shiny' app function with interactive displays for summary and analysis of variance regression tables, and parallel coordinate plots of data and residuals.

The Exploratory Regression Shiny App (ERSA) package consists of a collection of functions for displaying the results of a regression calculation, which are then packaged together as a shiny app function.


You can install ERSA from github with:



This is a basic example which shows you how to solve a common problem:

## basic example code

To use ERSA first do


Then construct a regression model of your choice.

f <- lm(Fertility ~ . , data = swiss)

This opens up a browser through which you can explore the regression model.

Here is a screen shot of the result:

To play around with ERSA on another dataset, check out the Shiny app on check out the Shiny app online. It uses the hprice1 dataset from the R package wooldridge.
