• How to do DOE with dependent variables

  Hello, I am not sure my DOE is good. I want to compare two different cell culture platforms.I have two different culture platforms and each plat form has different ranges of rpm and working volume.For examples, platforms A & B (categorical)For A, 100 rpm - 200 rpm / 100mLFor B, 300 rpm - 400 rpm / 25mLInitially, I had two factors like rpm1 (100 - 200 rpm) and rpm2 (300 - 400 rpm). Then, in 'model'...

• Sample size to meet specificity and sensitivity requirements

  Hi, I'm trying to calculate the sample size required for my test to meet the sensitivity and specificity requirements.I have a binary test that detects the presence of bacteria in water, if it's positive bacteria is present, if it's negative it is not present.I would like my test to have92% sensitivity (with 95% CI of 90-94%)and 90% specificity (with 95% CI of 88-92%)and I want the power to be 0.8...

• Dunnett's for Multiple Ys

  I am trying to get a script that will run Dunnett's on multiple Ys automatically in fit model, my issues:   If I change the multiple comparisons part where the factor and level is not a variable it works but only for the first Y, it will not repeat the Dunnett's part for the remaining Ys.   So my questions:   1.  Why doesn't this work like the fit model with a variable being used for the factor an...

• Process screening platform change between JMP 15 and JMP16

  Hello,  I use the process screening platform in a script. S = Response Screening( Y( Eval( Expr( YParamList ) ) ), X( :Split ), practical difference portion( 0.05 ),save compare means );Then I use the output table to draw  plots of significant parameters. However since we use JMP16 it doesn't work well. It seems that the name of table, the order of tables (the active table after execution is not t...

• Using DOE to optimize a process

  Dear JMP-Community, I want to optimize a process. I have 5 factors (X1 –X5), whereof one is a hard-to-change factor (X3) and 10 response variables (Y1-Y10). Responses are measured with a trained sensory panel (8 – 11 assessors). Each assessor can evaluate 3 samples per whole plot (=day). The assessors evaluate the intensities of the defined attributes (=responses) using an unstructured line scale ...
