Is it relevant to use the Stepwise platform with a nominal response?

Hello everybody, I want to do variable selection before running a nominal logistic regression. However since "nominal responses are treated as ordinal responses in the logistic stepwise regression fitting procedure" I wonder if it is correct to use the stepwise process with a purely nominal response variable. Why is not it possible to use the Stepwise platform directly on a nominal response? What ...

How do I analyse a two-way ANOVA with two blocking factors

I have an experiment set up as a randomized complete blocks, where replicate groups of plants are planted in trays. The tray is the blocking factor, and within each tray there are 24 cells, where I planted groups of plants. In each cell of a tray, there is a focal plant and neighbour plants. Focal plants may be either Tall or Short, and neighbrous (collectively) can be Tall or Short. So treatmen...

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)

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...

Setting "ignore errors" flag on a formula column

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 ...
