How do I conduct an orthogonal polynomial analysis in JMP?

Question

Hello,

I would like to conduct an orthogonal polynomial analysis to check for response (linear/quadratic) of egg production to increasing doses of a product.

Dosing is not equally spaced (0, 100, 300, 500, 1000 ppm).

thanks for your help.

Thank you for your reply.

I couldn't perform the multiple correspondence analysis - it says the data (eg Av Egg Weight) added to the Y-axis is of the wrong type or the analysis is of the wrong type!

I've attached the data for reference.

Possible answers depend on what you mean. Take a look at the attached table, and run the script it contains. If this is what you are after then you should start by reading about 'Analyze > Fit Y By X' (when X and Y are both continuous variables).
