      Is there a location within DataGraph to obtain the actual p value for a linear regression “fit command” analysis?  I see most of the other statistics are provided, but not the p value.  Am I missing something?

          We just uploaded an example file that demonstrates these calculations. (Download from File > On-line Examples)

          “Hypothesis testing for Linear Regression. This file can be used to explore the relationship between p-values and confidence intervals for linear regression parameters….”

          The output is set up in the data table.

          And you can also explore graphically.
