How to obtain all parts of a string except for the last segment?

How can I get all parts of a string except for the last segment? For example, given "This is a sentence," using -1 can get the last word "sentence." Using [1 3] can get "This is a," but since the string's length varies each time, the positions are not fixed. Is there a way to directly get all parts of the string except for the last segment? Names Default To Here( 1 ); Word( -1, "This is a sentence...

I would like to perform a modified Poisson regression using JMP.

I would like to perform a modified Poisson regression using JMP. I would also like to display confidence intervals using robust variance. Could you please explain in detail how to do this in JMP? Thank you very much in advance.

JMP v19 Graph Builder performance with large tables (13M+ rows)

I’m running into significant performance issues with Graph Builder in JMP v19 when working with a large table (~13 million rows). In JMP v18, I was able to interact fluidly with the same dataset — panning, zooming, and switching variables were all manageable. It’s a single table of about 13M rows, with a couple-dozen columns, on a pretty heavy workstation with 64 GB RAM. In JMP v19, however, I’m ...

How to Get Continuous Line Plot in Graph Builder for Multiple Variables in X

Hi all, I'm struggling with a behaviour in Graph Builder that I don't understand. I want to plot a line graph across several variables. When I select my variables and drag them to the "X" field I get this graph. The issue I'm having is that sometimes one of my variables completely changes the behaviour of this plot. In the previous plot, I included X_1 to X_10 but in the plot below I've includ...

Automatically Size/Scale Background Image to Fill Graph upon any change

I have pasted a background image into a Graph Builder chart. I would like to, by default, always have the background image "Fill Graph", no matter what changes are being done to the graph. Is there a way to do this? Manually I get to the option by right-clicking the graph and going to Image >> Size/Scale >> Fill Graph.

F Ratio Calculation Before Entry under the Combine Rule

In stepwise regression using the Combine rule,
could you please help me understand how the F ratio for the child effect (Material B–C) is computed before it enters the model?
In my results, this value is F = 0.103779 (as shown in the screenshot). It doesn’t seem to match the F ratio that would correspond to the larger of the two p-values mentioned in the JMP documentation —
that is, the joint probabi...

Slight difference in p-values under “Combine” rule (before vs after entry)

您好，
我注意到在使用逐步回归和组合规则时，p 值存在细微但一致的差异。
在我的示例中（见下方截图），材料 (B–C) 显示的效果为：
输入模型前：Prob > F = 0.75127
输入模型后：Prob > F = 0.75103
F 比和自由度完全相同 (F ≈ 0.104, df1 = 1, df2 = 16)，所以我想知道为什么 p 值不相同。
我的猜测是，JMP 在候选效应进入模型之前计算候选效应时会执行“临时完全拟合”或增量投影，这可能会与最终的完整模型拟合产生微小的数值差异。
有人可以确认 JMP 在组合规则中计算候选 p 值的方式是否确实如此吗？以及这个细微的（1e-4 级）差异是否是由于内部精度或四舍五入造成的？
谢谢！ JMP 专业版 17.1.0

Prediction Profiler issue

@malcolm_moore1

I have a question regarding an issue with the Prediction Profiler, and I’d appreciate your help in understanding it. I built a model using the Fit Model function, where three responses were fitted separately, each including multiple effects in Effect Screening mode. After building the model, I identified the most significant effects and checked the residuals for normality. Once the...

WINDOWS > JMP 17.2 > Custom Report Window > Save Presentation ==> Only portion saved to PPTX

Hi JMP Community, I built a simple report with a graph builder plot, a multicolumn text section, and a summary section (see below) that I would like to export to PowerPoint. While I can save this report as a PDF without any problems, when I save it as a Presentation/PowerPoint manually or within the script, JMP generates slides that only contain the plot section and none of the text (GO GENES and...

How do I get z-scores for each protein in the Longitudinal dataset? (JMP Pro 18 Free Student Edition)

For context, I am running analyses on a proteomics experiment. I have two datasets: Intraday (comparing AM to PM), and Longitudinal (comparing Day 0 to Day 30 to Day 90) for protein concentration. For Intraday, I have 600 proteins I am looking at. For Longitudinal, I have 68. I want to find out the magnitude of change between the time points for each protein, so I am trying to find z-scores. I am ...

SPC Sampling Rate Determination

I am trying to determine an appropriate sampling plan for a manufacturing process which has a dimensional in process control (a length). There is a USL and LSL with a target. Cpk and Ppk are both coming in at >2 on a sample size of >2000 units across two mfg. lots.

We sampled at a rate of ~5%. I’m trying to figure out what the minimum sample rate is to ensure quality (95/95 confidence coverage). H...

Moving Box Smoother (Graph Builder)

I'm using the moving box smoother in JMP 19 graph builder and can't seem to find any definitive documentation on how to interpret the 2 shade gradations surrounding the smoother curve. Are these confidence bands? If so is the lighter (wider) the 99% band and the darker (narrower) 95%?
