• Negative numbers in prediction profiler when zero is limit

  I have attached an 8 mixture custom DoE in which 3 ingredients are constant.  When I run the model, the prediction profiler predicts the maximum Y1 & Y2 within reason of the actual maximum.  But when I minimize the desirabilities, I get negative values.  How is it getting these numbers and how would I prevent any predictions falling well below the actual low response values?

• How to estimate standard deviation for large population from small samples size

  HiIf I have the distribution of data from small sample size (e.g. N=250, 1000), and would like to estimate the distribution (e.g. sigma) of data on large population (e.g. N=1 million)?   What is the confidence level / error on the prediction ?(Assume the distribution is Normal distribution or same shape for small/large population)Thanks!Kelvin

• how to plot an equation

  Hello,I'm a new user to JMP and I have a simple question to seek your help. I would like to ask JMP to plot a graph using an input equation, how do I do that?The equation is as follows:(c1-constant1)/(constant2 - constant1) = (constant3 * c2)/(1-(1-constant3)*c2)where c1 and c2 = column 1 and column 2 respectively.i.e. I have two columns of experimental data (column 1 and column 2) and ultimately ...

• Generating random data based on correlation matrix

  Is there a method to have JMP generate random data that fits a specified correlation matrix.  I want to be able to specify the desired correlation matrix (and sample size), and generate random (multivariate normal) data that is based on the specified matrix.
