Constrained least squares and exponential fitting

I am looking to fit Y ~ 1-exp{-[C1*(x/Xmax)^1+.......CN*(x/Xmax)^N]}. The order could be anywhere between 6 to 12 (max value of N). But before generating the fit, I need to estimate the coefficient using modified LSQ. I looked at the exponential fit (analyze fit Y-->X) and tried to enter a formulae but I do not want to directly fit the exponential curve, rather I want to estimate the best fit coef...

Two-way repeated measures ANOVA

Hi,I did an experiment with 10 rice varieties and 4 water treatments. All the combinations of variety x water treatment were were tested and each combination had 4 replica's. I now want to test the signifcance of water treatment variety and their interaction.I think I have to do a two-way repeated measures ANOVA (because both variety and water treatment are within-subject factors) but I don't real...

Data Manipulation - How do I remove Initial Offsets specific to a col identifier

Hi all, My first post! I have a regular set of data I process and have been doing manual manipulation in excel before importing and plotting in JMP. I'm sure someone has a better way :)I measure 16 DUT's and record offset data for each dut. I would like to zero out each individual DUT offset based on the first 100samples of data and apply this to all rows of data. I would like to remove the initia...

How many center points to add in a design?

I understand we add center points to designs to test for curvature in design. Does adding more than 1 center point to design helps with better estimation?

capability analysis using control chart builder

I got machine in lab for which I have set limits and I am trying to find out what is the probability of failing in the the future or if I'll get readings out of spec. First I used control chart builder and then did capability analysis and I got the following nonconformance table. Is this telling me that 2 out of 100 reading will be out of spec? What is expected within %?

Graph Builder Mean Line

I have a "points" plot in graph builder. I would like to add a mean line to the plot automatically, like one can do in Fit Y by X by selecting Fit Mean. I want it to happen automatically because I have a local data filter that I want to use to filter my data and each time I do so, I want the mean line to update with the mean of the filtered data. Basically, I would like the Mean Line to behave the...

Chi square or Cochran's Q test

Okay, so i have to decide whether i should use chi-square or Cochran's Q test for one of my study.If i assume meat as experimental unit (EU) and impose 6 different wood smoke (like apple smoke, cedar smoke, hickory smoke etc.) on EU and consumers (people) act as observational unit (OU). I have 10 consumers and each one will taste each treatment (6 treatments) and respond liking (9 point scale), an...

using loop to display a tab box inside a tab box

Hi guys , I am trying to display a tab box inside a tab box using loop Below is my code , however it does not allowa me to use array , only variablee allowed . New Window( "Result", display = Tab Box() ); For( j = 1, j <= N Items( stepname ), j++, step = Substitute( Char( stepname[j] ), "DataTable(\!"Specname=", "" ); display << Add( step, main[j] = Tab Box( ) );

Graph Builder composite graphs

In Graph Builder, I would like to create a composite graph consisting of four panes in a 2x2 arrangment. I'd like each of the panes to have a different y-axis, whereas both have the same x-scale. I can get to 2 rows x 1 column with overlays.But when I double up the x axis, I'd like the overlay to go away, so I just have a single parameter in each pane. Instead I get this:
Is there a way to get 2 x...

Selecting Number of Clusters in Hierarchical Clustering

One way to select possible number of clusters in hierarchical methods is to identify the relatively large changes in distance as number of clusters change (see table below). When I look at the actual distance measure from the table (clustering history below dendogram), there is a bigger jump from 3 clusters to 4 than from 4 to 5 (smaller), suggesting 4 may be the right decision. However, when you ...

Beta Generalized Regression and adjusted chi-square values

I have a data set from a two-choice rodent feeding trial. We were testing the effectiveness of 10 deterrents by coating them on seeds and offering them to rodents alongside control seeds that were uncoated. The explanatory variable is which of the 10 deterrents the treatment seed was coated with, and the response variable is the proportion of control seed and treatment seed consumed. The question...

DF Dens for repeated measures ANOVAs

Dear JMP Community, When I run repeated measures ANOVAs with JMP (RMS, with Subject as a random factor), I have noticed that when a certain factor is crossed with Subject, the corresponding DF Den stays independent while the DF Dens for the other factors are put together as “Residual”. Please see Images 1-3 of the attached file on how “DF Den” under “Test Denominator Synthesis” change across imag...

Partition and Pruning

I'm working with a dataset of about 27,000 rows and am trying to use 9 factors to predict a response using the partition function and a decision tree. I'm using both k-means and validation. When I tell JMP to Go, it will split 100-200 times, however the Split History shows me very little improvement after about 20 splits. For what I'm trying to do, I want to back up to the 20th split, but I don'...
