Graph Builder/Smoother Question

When using the Graph Builder, I like to use the smoother when plotting a Y variable against date as the X variable with multiple Y's for each X value. How do I get the smoother to work when I change the Summary Statistic from Mean to N? Currently, when I change to N, the smoother for Mean stays on the chart and I want the smoother for N instead.

Change X-Axis Label Orientation

Hi, In the variability chart, I am trying to change the text orientation of one of the X variables. Here is the part of the code.

Graph builder: add p-values

Hi, I am plotting means of a response of three groups (BASE, LIV, SHAM) over time using graph builder. So far I have been able to plot the means and STD, as you can see. I would like to add p-values from a t-test comparing LIV vs. SHAM at each time point without having to do in manuallly by adding a text box to the image, similar to what I did here. Is this possible? My current script is...

Color Cells With Missing Value and Greater Than Value

Hello Forum! I want to color cells in columns that start with "Diff" that has a value greater than .1 OR has a missing value (.) The number of columns that start with "Diff" will grow as the data set grows. Here's what I have so far but probably won't work in the long run as the # or columns grow. Names Default to Here(1);dt=current data table();dt:Diff T00 << color cells("Red", dt<<get rows where...

HELP!? How to add sample size and % above USL and below LSL in graph builder?

I have plotted 2 data sets in graph builder that looks like this: The USL and LSL were automatically placed via the spec limits I set in the column properties and adding refrences lines to graph. I then additionally added a Marginal USL (MUSL) manually in graph builder. To this graph, I would like to add a label or note with the count/sample size for each data set as well as the % of points ab...

Prediction formula null values

Hello, After saving my prediction formula from GenReg, I'm seeing about 80 percent of my dataset has null values (.) in the predicted values column. I suspect it has something to do with several "levels removed" in some of my significant predictors. Any advice on how to handle this or how to pivot from this in order to arrive at a higher yield (of predicted values) would be appreciated. Thank you...

Overlay markers on multiple graphs

These are the graphs that I'm working in. I'm new to JMP and I've been trying to figure out how to make all three of these graphs have the same attributes that the bottom one has from the legend. I need all three graphs to use the same overlay markers and colors. Any help would be appreciated!

Axis in Loading plot of PCA in JMP

Hi, I am relatively new to PCA analysis as well as to JMP. How can I change the PCA loading values on the x and y axis of the plot that JMP rovides when you do a PCA analysis? Right now the default is PCA1 on x axis and PCA 2 on y axis. I would like to plot PCA3 on y axis and get a similar plot with the vectors showing in diff directions, labels etc.

.jsl scripts will lock files even while set to read and execute permissions only

I am having an issue where an add-in script which runs another script via the include(); function is locking the included script file while other users are running it. This renders me unable to update that script. I tried setting the permissions on the repository and the file as read and execute only but it still locks when other users access it.

Sub-sampling data analysis in JMP

In Biology (Plant Sci. and Agriculture) usually we have sub-sampling data for replicates. It's very difficult to analyze these data in commonly use Stat S/W (SPSS/Minitab) because MSS(Error) is calculating wrongly. Without taking averages of samsamples, the easiest S/W for this is using JMP and I need some assistance for this. I've found very useful Youtube video about subsampling in JMP (CRD: S...

Conceptual question about the profit matrix

This issue has been discussed previously, but I keep finding myself confused about how to use the profit matrix. My question is conceptual in nature, so let's just use some simple numbers. Suppose I have data on customer churn and I build a predictive model for churn (the particular technique does not matter for this question). My decision errors are not symmetric, however, so I want to modify ...

Cox Proportional Hazard - adjusting risk ratio with std dev

I'm working with someone who is using SAS and I'm trying to do the same analysis in JMP. When I questioned their hazard ratio they said it was adjusted by the standard deviation. They commented:In order to obtain results in units of 1 standard deviation – you simply get the standard deviation value for parameter of interest and introduce it in the PH regression statement, for example:proc phreg ...
