SUBMIT YOUR IDEAI took a course on Udacity and the focus was on using the Predictive tools, examining the output of the reports, and deciding which variable to use. After I came up with a solution I wanted to check against the solution, which starts with the Data Investigation palette. My list of predictor variables was very close to the solution file.
Also, I compared three different models and used the Forest Model, which had better correlation and error measures.
I had to change the Linear Regression tool to use the 1.0 version in order to get an output that matched the solution file.
Even though Forest Model has the highest accuracy, I had to use Linear Regression Model to match the exact output given.
