• F-Test for Linear Relationship

  HelloI'm trying to perform an f-test to check if there is a linear relationship between 2 continous variables at the 0.1 level. I've done Fit Y by X -> Fit Line and have my answer of Prob > F = < 0.001. However when I change the alpha level under the linear fit level none of the numbers change. Am I doing something wrong because I thought the ANOVA results should change as alpha changes.Thanks

• Variability Charts - rotating text in the x-axis grouping?

  For the variability chart graphic, the x-axis groupings have previously been capable of 90 degree rotation to make the text vertical.  I have tried scripting it in and just right clicking the box and checking rotate text.  The text now just shifts slightly instead of rotating.  My scripts I have been using for a couple years no longer do this and I can't even get it to rotate when creating a test ...

What I don't understand is why regressing the same variable as least squares fit in JMP produces a different adjusted R^2, coefficients, p-values, etc.Can anyone help me add...

• Line and bar in overlay plot?

  I am trying to create an overlay plot that uses a line for the left axis and a bar for the right axis.  I can plot two lines in an overlay but not a line and a bar.  I can plot a line and a bar in a chart (as opposed to the overlay platform), but not get them on seperate y axes- they are both on the left.For what it's worth, I am trying to do this in JMP 8 and would like to find a scriptable solut...
