Predicted values for conversion over 100%.
Hello everyone, I’m running a Central Composite Rotatable Design (CCRD) in JMP to optimize a chemical reaction, with conversion (%) as my response variable. By definition, conversion should range from 0% to 100%. However, my fitted model sometimes predicts conversion values greater than 100% (and occasionally less than 0%) for certain factor combinations. Here’s what I’ve done so far: My experime...
