Help me make sense of the significance in Chi-Square Analyses results

Hey all,Here I have run the presense of a car passenger (1 = front seat, 2=back seat) against casualty severity (1 = fatal, 2 = serious, 3 = slight). I am having trouble understand the results. I understand that the expected count and the actual count is what I'm interested in, but how do I detect whether the difference between those two counts is significant. Thanks in advance!

Viewing "Weighted N"

Hello,First of all, I should say that I am an Engineer with a very basic knowledge in statistics (perhaps thats why I am using JMP :) I have a data table with 90,000 rows and 12 columns. One of the columns has a pre-selected role as "Weight". The dataset I have has been sampled from a series of events with each event having its own "Weight". In our literature, it is common to publish Tables with "...

Saving R-Square values from smoothing spline fit

Hi all, Is there a way to save the R-Square value from the smoothing spline fit in JSL? I'd like to be able to reference it at a later point. Thanks!

Formula to toggle value (1 or 0) in new column based on change by row in existing column

I have a question on creating a formula to do something in JSL that I do very easily in Excel. If I were to have Column A and I want to generate Column B, I would put a zero in B1 then add the formula: =IF(A2<>A1,IF(B1=0,1,0),B1)into B2 then copy down the column. Is there a formula to do that in JMP? I have tried Lag() but it doesn't give me the results I'm looking for.

DOE - ELISA method - 4 PL modeling

Dear JMP Community, My question is about a DOE performed on ELISA method.The response is the Absorbance and there are 3 factors which are dilution of different reagents (standard, parameter B and parameter C) - Refer to graph attached to visualize the type of data I have.I’m looking for optimizing the three factors to get a plateau equal to 2 for absorbance. But I would like also to be at “the beg...

Non-parametric Mixed Model

Hi everyone, New to the forum. I've been using JMP for a while now and I have encountered my first problem. Maybe it's not a problem to any of you, but I don't know how to run a non-parametric test on a mixed model. My understanding through the fit model platform is that this is a parametric method. However, there is no way to transform my data. I have a response, y, a fixed factor, and a ra...

I want to use LASSO and Group LASSO in JMP

I'm involved in a project where we are applying lasso to build a logistic regression model from a "black box" set of predictors. I need to get JMP Pro before trying out JMP's implementation. I'm doing all the analysis in R at present. Does JMP Pro also include group lasso? I've found through using JMP Cluster Variables (CLUSVAR) that I can naturally group my predictors prior to group lasso. F...

Mean separation letter from test slices

Hello!

How do I get the mean separation letter in for each level of a factor when interaction is significant? For example, if I have A*B interaction and I want to get the mean separation of B at each level of A, how do I get the LSD letters in JMP? I can do test slices and that will use the DF of the full analysis, but this does not shows which mean of B differs. If I do multiple comparison: How ca...

repeated-measures ANCOVA: How to perform the analysis when the parallel slope assumpt. doesn't meet?

Hi all,I need to perform the ANCOVA for a repeated-measures design. I tried to adapt the Julian's ANCOVA procedure showed on the https://www.youtube.com/watch?v=mApbp1RDy-U to my study case (repeated-measures design). Initially, I did the following actions: 1. In the Fit Y by X dialogue: I selected VAR_Y as "Y, Response" and VAR_X as "X, Factor";2. For "Group by" I selected the variable Timepoint;...
