Hello,

I am displaying the input necessary for the script:

I see that if I was performing a One-Way ANOVA that I would simply place the means of each of setting of X1 in the boxes.

e.g.

Temperature (X1) : [ 90, 100, 110, 120]

I would input the average response at Temperature 90, 100, 110, 120 into the boxes. Let's say the average response was 9, 10, 11, 12.

However, what does the Extra Parameters represent? Would this be if I had two factors instead of a one factor ANOVA?

Thank you,

Nate
