Center points in 2k factorial experiments

HiCan someone pls help me to understand how much center points should I have in 2k factorial experiments? e.g. how many center points do I have in 2^3 factorial experiment with 1 replicationhow many center points do I have in 2^4 factorial experiment with 1 replicationhow many center points do I have in 2^3 factorial experiment with 0 replication etc..ThanksRamon Bamer

Parsing JSON data

Does anyone know of an existing script or code snippets to get me started on parsing JSON data? I'm particularly interested in how to handle the process of reading each key:value hash and writing it to the JMP data table.Here's a sample with a group ID number, followed by the timestamp:reading hashes.{ "1":[[1341118805, 0.654], [1341205195, 0.654]] , "10037506":[[1341118820.000, 0.900], [13411188...

reading results of Augmented Dickey-Fuller Unit Root Test

Dear fellows:
With ARIMA procedure, I can carry out Augmented Dickey-Fuller Unit Root Test. However, I do not understand 'rho' in test output and I can not find any related information in sas documents or statistical books/literatures.

I assume that 'rho' is coefficient on 1st lag and has range [-1,1]; and I assume that unit root test is to find out 'rho' equal to 1 or not. For instance, Y(t) = ...+...

R-square

Let’s say we want to determine if Y (continuous) could be predicted by other metrics (X1, X2, X3-all continuous).
We have table with 31 rows, each row contains data about X1, X2, X3 & Y.
We want to find out what are the metrics we should use as inputs to Y while we want to account for at least 81% of the variation in Y.
We fit the model and looked at the "summary of fit", there we see R-square of ...

Dice Rolls Simulation for Multiple Dice

Is there any chance I could get the script for altering the Dice Rolls simulation under the JMP Teaching Resources to have 2 or 3 dice rolls and plot the mean instead of just one roll?

How do I search for a specific column name for "process", sperate by a known "sample label" and a known "by"

Hi everyone,I've tried to search before I asked. I'm learning and very very new with the JMP software, we are using version 10. What I'm trying to do is make a script that will look in any given data table for specific column names and cast the columns into roles for a control graph IR. In the control graph I want it to find the column and use it for the "process" portion. Then use sample labels t...

test statistics on odds ratios in logistic regression

I've been using logistic regression with multiple categorical predictors. I'm particularly interested in the odds ratios, and I understand how the odds ratios themselves are calculated, but I'm having trouble understanding how the test statistics associated with each odds ratio are calculated. JMP gives the disclaimer "Tests and confidence intervals on odds ratios are likelihood ratio based." M...

What robust methods are common for Process Capability Indices for Non-Nornal distributions?

In Europe, we found it common to use Cpkn as a non-normal Cpk metric, where mean was replaced with median, and stdev was replaced with IQR/1.35. For some "regulatory" or "customer" reports, this seems to be accepted rather than the usual "torture the data until it says its normal" approach with transformations. Does anyone have similar experience or better ideas? (Note: any use of capabilit...

Graph Builder Remove Variable

Hello,I am trying to use jsl to remove the x-axis variable and replace it with a different one. It looks like I should use the GraphBuilderBox <- Remove Variable() tool, but since I change the x-axis variable multiple times, I do not know its name and would like to use the Remove Variable(Role("X"), Position(1)) method, but this does not work. Any assistance would be appreciated.Thank you,Martin

How to calculate average (median) of a group of variables to get the eudlidean centre

How would I calculate the shape of the average (using the median) of a variable from a group within a data set? I need a certain function for calculating the centre of gravity (centroid) or Euclidian centre of this group of variable.
Many thanks!!
