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
