Process Help: Correlation and Regression

Hello!

I have the following data (74 observations) and am trying to identify the process and operators to conduct an exploratory analysis (Correlation and Regression) of the relationship between the president's political party affiliation and this consumer good's Producer Price Index value which is averaged over each year annually. I also have the PPI values quarterly and monthly for the same years which will be assessed using the same process in hopes of a more statically significant value.

- Additionally, how to identify which President had the largest change+/- in PPI over their Term and which year (assuming I'm using monthly values for PPI)?

    Hi!

    I would first calculate the yearly change of PPI. I assume the formula for that would be PPI_YrAvg / previous(PPI_YrAvg) - 1. You can do this in Excel or in RapidMiner with Differentiate or Lag and Generate Attributes. 
    Here's an introduction to Generate Attributes: https://academy.rapidminer.com/learn/video/generate-attributes
    And two videos for time series calculations: https://academy.rapidminer.com/catalog?query=differentiate

    When you have the new column YearlyChange, you can easily use Aggregate to group by party and calculate the average, min and max yearly change.

    Regards,
