    How do I get a linear trend line model to show the correct y-axis intercept value?

    Greg Michalski

      Why won't Tableau (linear) trend line calculate the correct y-intercept value?  Here is a snapshot of output from Tableau (right) and an Excel add-in program (Megastat) that I use.  Notice both calcualte everything else (e.g., p-value, etc.) the same but not the intercept value for the line equation.  Any help is appreciated.  Thanks!!
