I have set of independent variables ( X1 , X2 ) and a dependent variable (Y) . I am using Multi linear regression to study the impact of X on Y . ( Detail : I would like to show both the magnitude and direction how a unit change in X1 results in change in Y )

I would like to know if there is a good visualization to share with the business folks ? I can only think of bar plot for the model coefficients.

Thanks

  • Could you be more specific about what aspects or properties of this dataset or your model of it you wish to visualize? "Impact" could mean many different things. – whuber Feb 20 '20 at 22:41
  • @whuber - Just updated my question. Thanks – Zebra Feb 20 '20 at 22:52
  • A closely related thread is at https://stats.stackexchange.com/questions/397183. Maybe that's the sort of thing you're looking for? It depends on whether you need to show the data in your plot. – whuber Feb 21 '20 at 00:08

I'll outline a few ways to do this.

My favorite way is to plot the coefficients and the confidence intervals. I know that business people are not always statistically savvy, so while in my opinion this is the way to present regression model results it may go over your partner's heads.

Another way may be to just plot some different lines under different values. Here is an example of what I mean. This way, they can clearly see that as V2 increases, the predictions decrease, and as V1 increases then the predictions do as well.

There are endless charts. I think the question is not "what chart do I use?" but rather "what information do I want people to walk away with?".
