Boxplot Whiskers Interpretation

Hello. By plotting Variability Chart and choosing "Show Box Plot", I believe the given boxplot is an Outlier Box Plot as described here. http://www.jmp.com/support/help/Quantiles.shtml Need to be sure of my understanding on this part below: Each box has lines, sometimes called whiskers, that extend from each end. The whiskers extend from the ends of the box to the outermost data point that fal...

Comparing multiple means using one way ANOVA when variances are unequal

I have 3 data sets and performed One way ANOVA to see if means between group are different. The ANOVA for the P-value is 0.13 and shows there is no significant difference between means, but the four test for equal variance test O'Brein, Brown-Forsyhe Levene and Barrlett have p-value equal to or less than 0.00723. This indicates variances are not equal. The Welch's ANOVA test also has a low p...

Curve fitting and normalization

I have got a data set which is positively skewed and therefore need to normalize it. I have got a wave form line with age and challenging behaviours present in Individuals with intellectual disabilities. I am totally new to JMP and advanced statistical procedures and this is a big step in requirement of my PhD research. Any step by step guidelines or videos in scale development, curve fitting, nor...

Graph Builder Overlay Color

Hi, In Graph Builder, how can I use the Overlay and Color options to change the color and marker for each data group? Changing the marker is useful to help distinguish data when there are many colors, which may be very similar to each other. For example, in the script below, it is useful use Overlay to separate data by age, and use Color to change the color and marker for each point, but if I us...

Changing Date Format

I'm trying to import data from an excel file where a column contains dates in a format that looks like "Monday, December 05, 2016, 2016 12:20:01 PM EST"I want to plot this data in JMP in chronological order. To do so, I believe I need to get the date into numeric continuous format. Does anyone know how to convert the date over? I've seen a couple date conversion in JMP, but non starting from the f...

Script formatting for Variability Charts

Hello, I am trying to script a series of Variability Charts in a single Window, which I could save to a JRN or pptx later. Each chart is intended to display the values (in Y) of different parameters (e.g. Height, Weight, Length) with different combination of independent X axis {due to this reason, I could not script it as By( :Parameter_Class ) } in a single Variability Chart platform. Probl...

Can someone help me with PC settings to improve analysis speed?

Dear friends,I have Intel Xeon Processor E5-1650 v3 (15M Cache, 3.50 GHz, 6cores) with windows 7.My system stop responding sometimes. For instance, I have just 12000 data points each with 95 columns. When I do a fit model with full factorial using just 20input variables, system stops responding. Also when I use multivariate analysis, parallel plots etc with the same data it is extremely slow. But ...

Why there is a constant component in the PCA formula

Removing values from a column

Hi All, I would like to remove values from a column. Normally, I would use a range check column property to do this, but with this particular column, it is also dependendent on another column's value. Is there an easy way to do this? I tried the code below, but unfortunately it makes the entire column blank except for the first row. I thought this might work because the "." represents missing v...

Odds ratios for multiway tables

On twitter earlier today, someone asked if the Cochran-Mantel-Haenszel (CMH) odds ratio (OR) test was available in JMP when the stratification variable is not the X in Fit Y by X. Anytime I need to go from two variables to more than two variables, the first place I look is Fit Model. The beauty of fit model is that not only can I use as many variables as I want, but I can consider interactions bet...

How to find ETA squared effect size for MANOVA?

Hello, Does anyone know how to calculate the eta squared value from a manova analysis in JMP? I know that the E and H matrices tab shows the sum of squares for each parameter, but which values do I use to calculate SStotal and SSeffect? In my model, I have 2 control variables (age and gender) and then a two way factorial. If only one of these variables (in addition to both control variables) is si...

Is there an easy way to get the FWHM (full width half max) of a curve using JMP?

Dear JMP community,Is there an easy way to get the FWHM (full width half max) of a spectral curve using JMP? Finding the minima and maxima are fairly straightforward, but then calculating the FWHM seems to be much more laborious in JMP, especially if the data is sparse and we would like to interpolate to get more accurate intersections between the peak and the FWHM value. In my case, the peak is o...

Co-Kriging with JMP and Matlab

Hi!I was wondering if anyone already tried to work with Co-Kriging, using JMP together with Matlab. As JMP only fits Ordinary Kriging Models (Gaussian Process with Gaussian Correlation Function), I would like to send data (generated with Space Filling JMP Platform) from JMP to Matlab, fit the models there (Matlab), and bring the MODELS back to JMP, to use inside Profile Platform. Do you have any e...

Interpreting canonical structure and scores in discriminant analysis

I'm trying to interpret the relative contributions of my variables in a discriminant function analysis of chemical data for three groups of rocks. In a stepwise, linear, common covariance discriminant function analysis I'm able to generate non-overlapping 95% confidence ellipses for my three groups with no incorrectly assigned data points using 6 variables. My understanding is that the scoring c...
