How to calculate the variance of the weighted sum of >10 components

Perl https://stats.stackexchange.com/questions/5392/variance-of-two-weighted-random-variables; the variance of A+B is: Thus, one would imagine that the calculation of the weighted sum of >10 components will be very very complicated. Was wondering whether JMP has an easy way to perform the calculation. Thanks!

Problem with grouping columns

Hello, I have some JSL code which includes double loop and a the end of the code includes a line which i want to group the columns but it doesn't do that. 1. How can I fix the code?2. When running the script is any way that the new table opens will be another one and not the original table? I mean I want another file will be opened..

The code and table are attached:

dt = open("C:\JMPCommunity\DataT...

how correctly use Graph Builder and Slider box in different windows

I would use graph builder in combination with slider to change the appearance of the plot. In the example below I create a window with a map and a slider box to change interactively the scale of the colors. I would use the script to create different windows (of course, even with different variables, but in the example this stuff is not needed). It works just for the last created window, despite I ...

DOE - Custom D-optimal Design with complex constraints

Hello everyone,I'v got four continous factors for a D-optimal Design (three levels for second order effects) with a geometrical background. Due to this not every combination of the factors is allowed and simple linear constraints are not applicable. Is it possible to import a table of all allowed combinations of the factors and their three levels and to create a Custom Design based on that table? ...

DOE L18 Design matrix

Hi, I am running a Screening Design of experiment to identify the key factors affecting the output variable. The DOE includes 7 factors. Out of which 6 factors have 2 levels and 1 factor has 3 level. JMP is suggesting the L18 Hunter design matrix. But if I review the design matrix two of the runs (15 & 17, 16 & 18 in attached picture) have the same factor settings. Can you suggest why this is the ...

how to generate an interaction plot based on parameter estimate output?

I am analyzing a set of data about graph performance. I am comparing surface graphs with non surface graphs. In this analysis I have two tasks, A and B. I'm measuring the absloute difference (=participant's answer-correct answer). ABSDifference is ranging from 0 to 100. Its distribution is like a half normal distribution. To analyze this dataset, I used Fit Model, ABS differnce as Y by Graph and ...

Combining two Data files

Hello Everyone, I have two separate data files (one for eye movements and one for performance on a task). I want to combine these two data files into one file so that I can analyze them with one another, but am running into troubles on how to get started. The two data files have nothing but the participant file name in common and have varying amounts of responses per participants (ie. The eye mo...

How can I import reference lines from a column to the X-axis

Hi, I have a large data set with a common time axis. I want to add a column with events that occurred, to display these events as a vertical reference line (on the X-axis). How can I do this? If I now make one graph, I need to manually copy all X-axis reference lines to another graph, I want an automated option to do this.The events will add extra information regarding the trends observed and will...

how to change the type and color of lines in graph

I am trying to show line of fit in graph builder for several sets of data. The data table have many columns, I want to show the column(i) vs column(1).Every column can be grouped by A1 & a, also can be grouped by B1 & b, but except column(1). The follow is the chart about column(2) vs column(1): I use the follow script to change the type of lines:Dispatch( {}, "400", ScaleBox, {Legend Model( 8,...

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;...

Time Series - Prewhiten

Hello Everyone, My question pertains to understanding what the terminology in JMP's prewhiten platform means.Also, understanding how that helps me determine an appropriate Transfer Function that I can use to test whether x causes y. JMP's prewhiten output shows three different ACF's labeled "Prewhiten Corr", "Noise AutoCorr", & "Noise Partial AutoCorr".
What is the Prewhiten Corr, Noise AutoCorr, &...

Fit Spline By Group: Save Spline Coefficients to Column?

Hi all--having an issue. I am using Fit Y by X to fit 5,000 separate regressions. I hold control, select red drop-down arrow, and Fit->Flexible, Fit->Spline and select, say, 0.1. This fits a spline to all 5,000 graphs with lambda of 0.1. I have 28 X values in each of 5,000 graphs, and I understand there are 4 different spline coefficients (A, B, C, D). I understand if I just had 1 regression...
