Sample Size Calculation

My current process is operating at a 0.01 defect frequency (e.g., 3 defects in last 300 units inspected). If I make a process change that could potentially increase the defect frequency, how many units will need to be inspected post-change to determine if a statistically significant difference in defect frequency?

Fishers Exact Test in JMP Pro

JMP Pro is reported to have the ability to perform the Fishers Exact test on tables larger then 2x2. In the case of a 2x2 table if the numbers are small the exact test is generated automatically (both in the regular and pro version). How do I access the Fishers Exact test in Pro when the table is larger than 2x2 (3x2 or larger)

need help identifying first nonzero column

I have a large dataset with around 30 columns of time-dated financial entries. I want to know which column is the first with a nonzero (no columns have missing data, but I want to get the first column with a positive value entry) value. I've attached a small made-up example with four time columns and a fifth column showing what I'd like my formula to result in. If the zero values were missing, ...

Re-ordering the script list saved to a Data Table

I have created a set of scripts for a given data table and I would now like to "re-order" the scripts as they appear in the top left area of the Data Table view. I can't seem to find anything on the forums or in the Help section to address this. Basically the scripts are listed in the order they were created/saved. Is there a method for sorting/adjusting the list after creation? Thanks in advance...

Chi Square test, correction for multiple comparisons

I have monthly prevalence data (n=30-120/month) for the presence of a parasite (2x12 contingency table) that shows a significant chi square. I'm interested in comparing specific months to see if there are differences. Using the filter feature in contingency analysis I can quickly get multiple comparisons. However that is without any correction factor applied to control error rates. I have seen...

I have a formula column (confidence interval from the nonlinear platform) that sometimes generates an error during evaluation:This error can not be captured in a Try() block.My work around is to set the Suppress Eval flag and manually evaluate the formula one row at a time but I would prefer to be able to set the "Ignore Error" flag on the column to suppress repeated error messages that occur.I'v...

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 ...

JSL How do I wrap the title text of a OutlineBox?

Hi all, I often use the Set Title() message to overwrite the OutlineBox titles of charts, distributions, etc. My first issue is that the OutlineBox does not support the Set Wrap() message. Is there any replacement I could use? To work around the missing Set Wrap(), I started inserting newlines "\!n" in the tiitle text. After doing this, I have noticed a second issue: Whatever number of newlines I ...
