Control Chart & 3 Sigma

With reference to the table attached: I have about 30 observations. The values have a std deviation of 0.534121. The average is: 73.93235. Now if I want to calculate the control limits based on the thumb rule of ± 3 sigma, the limits come out to: 72.3 LCL and 75.5 UCL.However if I plot a control chart with the table in the attachment, the UCL and LCL are calculated to be: 72.852 to 75.01.

Is there a way to extract columns used in a formula?

Hello folks-I'm trying to create a new button in my platform which would extract selected columns from a step-wise analysis and then build up univariate distributions of each selection. The limitation is that the extraction of columns selected and building the distribution is held to the specific column names in the list. I would like to be able to dive into the column to check if it is a formula,...

confused over JSL in expression form

I want to store a small table in another table so that a script that uses both in the same report can reconstruct the small one whenever it's called for. This seems a nice solution because then users of the table can also easily open that small, related table of info while only storing one datatable.I did get the following to work, after much gnashing of teeth over layers of expr() syntax....dt =...

Simulating data with random() formula

Hi,If I have a column of data (A) and want to simulate a test result on that column (from a normal distribution(SD of 10 and mean = the number in column A), can someone confirm it is right to do it with the following formula:Random norma()*10+AIf it's not, how can I do it?also, is there a way to enter the SD a RSD(%)??Thanks!Agnès

What is the format for parameters for the Random Normal Mixture?

Suppose I want mean1 = 20, Mean2 = 40, SD1 = 10, SD2 = 10, Probability1 = 0.8, Probability2 = 0.2. How do I put these numbers in vectors for the "meanvec", "sdvec" and "probvec"?

Mixed mode weibull models? Does anyone know if this can be done in JMP, where JMP would segregate the data automatically?

I am attempting to move my Reliability modeling to JMP, but one of the types of models we will occasionally look at is mixed failure mode (or multi-modal) models. I can't seem to figure out how to do this in JMP. I am also not talking about competing cause models (i can do those), but more where i would put my failures in, and allow the tools to segment my failures.Any help would be appreciated.

Degrees of freedom in post-hoc t-tests

Hi, I have a question regarding the post-hoc t-tests in JMP. I run a repeated measures ANOVA with one random and two fixed factors. The two-way interaction between the fixed factors is included. (Y=random(A) + A + B + A*B). Following a significant A*B effect, I use the 'effect details' option to do post-hoc t-tests, Bonferroni-corrected for the number of comparisons. But. When I chose 'detailed co...

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...
