MTCARS Analyzer is a Shiny App to predict MPG based on car parameters.

Its main features are:

• Linear Regression plot
• Prediction based on a value of X
• 3D scatterplot for exploratory purposes
• Interactive regeneration of charts

DISCLAIMER: Please do not rely on this app for your next car purchase.

Here is a screenshot of the input form.

.

• You can choose X, Y, Z axis variables on the left side panel. 3D Scatterplot will update.
• For linear regression model choose X, Y variables where Y is dependent variable X is an independent variable. The single-variable regression plot will update accordingly.
• To predict a Y value based on a value of X use the numeric box for X. The result is indicated with a large red marker.
• To simulate errors in real-life distributions change the value of error input box. The predicted Y value is randomly increased or decreased. If error is 0, the predicted value follows strictly on the regression line.

Here is a basic code to show the regression modelling

If you use this app you can predict MPG based on car weight for learning purposes. Thank you!
