Multiple File Import Auto-Naming Data Table

Hello All, I'm writing a script where I start with a 'multiple file import' of a folder of .csv files. I will periodically be getting new .csv files that I would like to add. These files have a series of letters and numbers (i.e chghistory0857-786.csv, chghistory0956-783.csv, chghistory1008-805.csv, etc). The issue I'm running into is when I run the 'multiple file import' script, JMP creates a dat...

How to choose heredity rules in definitive screen

Hi, When performing a DSD, you are given the option for applying rules of "obeys strong heredity" for quadratics, and for interactions. I believe that this limits the model and allows only for interactions that contains both as main effects. I'm not positive how this works for quadratics unless it only allows for quadratics that are found to have a main effect as well. When evaluating your DSD, ho...

Help about sample size calculation

For my study, the primary endpoint is to determine the proportion of patients who experience a beneficial effect after receiving the treatment. We have established a null hypothesis proportion (퐻0) of 0.5, indicating our expectation that approximately 50% of the patients will exhibit a beneficial response to the treatment post-intervention. This figure serves as a clinically relevant cut-off point...

How to generate capability box plots for multiple process qualities?

Hi, I have the data table set-up as attached where my end goal is to generate the cpk/ppk values for each grade based on numerous quality (in this case density, roughness and strength) and also generate the process capability box plots. I am able to generate those in 'process screening' however unable to do the same using process capability platform in the 'analyze' section. I've successfully do...

Can I add error values to a response variable in Custom DOE?

Hi there, I'm working with Custom DOE, and I've collected data for my response variable that I want to input to generate a model. I've also collected data on the error associated with the measurement of that response variable (for each data point) and I was wondering if there is a way to take this error into account. I haven't been able to find any details on this so I figured I'd ask here -- I'm ...

One DOE for two contradictory research questions?

Hello,I want to study a chemical reaction, which occurs in the frame of a measurement as a side reaction. I want to know, 1) which factors and which values give an optimal result and 2) which values give a minimal result.It seems that I have two possibilities:Two DoE Plans for each questionOne DoE Plan for both.However, to get both results, all kinds of parameters need to be studied thoroughly an...

How to categorize the same ID in row with other columns?

Hi, I have the data set that the same ID in multiple rows. Each rows had 1 to 3 categories. The columns represent costA to costZ that I need to stack in the same Cost column. However, I need to generate group by category 1 ( 1 if category 1 < 2000, 2 if category 1 = 2000 - 4000, 3 if category 1 = 4000 - 6000, 4 if category 1 = 6000 - 10000, 5 if category 1 > 10000). However, I need to delete categ...

LCA appears to treat ordinal variables as nominal

When I run cluster analysis --> LCA with ordinal variables (numeric, ordinal), the probability formula appears to be treating the variables as nominal, rather than ordinal. For each variable, there are 5 levels (i.e., 1-5). If being treated as ordinal, wouldn't the probability formulas reflect an order for each level where 1 may have the smallest probability and 5 the largest? As you can see below...
