How to evaluate the defect rate and overall defect rate with the varaibility of the model?
Hello, I am currently validating an analytical method and more specifically the robustness of the method. We should have been evaluate the robustness of the method during developement but for this old one, it has not been performed.To evaluate the robustness of the method, we perform a placket burman design with severals HPLC factors and we get as response the concentration of the analyte.To study...
