Which Algorithm to use? Let Model Compare Show you

First I reviewed this Exponential Regression. It says “Exponential regression can be used to find an equation that best fits the relationship between a group of random variables”.  I found some banking data from Amazon, shown below:


Since the data is in a .CSV file, I have several algorithms available:


Which one to use? Predictive 2.2 has a model compare feature. 


Above shows the configuration for the exponential regression

I followed the SAP Analytics video to set up the rest of the model compare:

This is how my model comparison looks:


The start next to Exponential regression model shows that is the “favorite” model over the R-exponential model

The algorithm also shows the SAP exponential regression algorithm has a higher score over the R-exponential algorithm:


There will be times where you will want to use the R-model or import a custom R model, but in this example, the SAP algorithm is preferred.

I don’t think this is enough to enter the Data Genius contest but maybe it will give you some ideas?  You can download a trial of SAP Predictive Analytics
