Possible to increase floating point number precision?

Hi. Is there a way to specify the floating point precision JSL uses when performing calculations? That is, the number of significant digits used. For instance, on my computer 1 minus 1e-15 equals 0.999... (15 "9"s). But if I try 1 minus 1e-16, I just get 1. x = 1;y = 1e-15;z = x - y;Show(z); //z = 0.999999999999999 (aka 15 decimal places)y = 1e-16;z = x - y;Show(z); //z = 1Thanks...

What is the fastest way to populate a new column with character values?

Hi, I have a script that does an advanced table concatenation, and I want to add 'source columns' to indicate the original table names. I have a few methods that work but all are slow for large tables. I also tried a formula method but it wasn't quick either. Is there some other trick I can use?Example below very closely matches what I'm doing. Data table sizes of 1M rows are not unusual, so I'd r...

Changing the font size of point labels in a Contour Plot

Hi,In a Contour Plot (or for that matter any chart in which points are automatically labelled with the contents of one or more specified rows and/or columns in the data set from which it is generated) is there any way to change the font size of the labels?I know I could increase them manually with a Control-Shift-Plus key combination, but doing that increases the font size in every open window, wh...

help!! How can I change each variables plotted points to something other than solid circle in graph builder?

help!! How can I change each variables plotted points to something other than solid circle in graph builder, such as an open circle or diamond? Attached is an example of an older graph (created in older JMP version) with the variables points marked differently and an example from newest JMP version.

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...

Problem using Graph Builder with Data Filter

Graph Builder works succussfully with the Data Filter adjusteing the plotted points properly when the Data Filter slider is moved. Also, the values of the statistics using the Caption Box adjust with the Data Filter slider as expected. So far, so good. Then I wanted to plot the mean of a column using 'Customize' and 'Y Function'. The following is the extracted script:Add Graphics Script( 3, Desc...

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...

Generalized Segmented Distributions

A former classmate of mine from Graduate School has recently published a paper on Generalized Segmented Distributions. Utilizing this method, the distribution can approach any continuous density function of arbitrary form. The method is particularly effective in fitting data with sufficient observations that are skewed and/or multimodal. The paper can be found here:The General Segmented Distrib...
