• Sample Size and Power (One Sample Proportion?)

  Dear Community,I write you for a specific topic on sample size.I know that JMP can support it… but… I need some details.Question.I have the Process A;I process 100 samples and 10 of this failed the final test. This means: process Yield = 90% (or process scraps = 10%);I change some parameters on the process to eliminate the scrap. This means that I want: new process Yield = 100% (or process scraps ...

• Arbitrary Operations (functions etc.) on each item in a list

  Is there a more simple way of applying the same function on each item of a list rather than iterating through a list?For example:stringlist = {"1", "2"}; numericlist = {}; for (i = 1, i<=N Items(stringlist), i++, numericlist[i] = Num(stringlist[i]) ); show(numericlist);Is there something simpler, something like just saying:numericlist = Num(stringlist);but this obviously doesn't work. Any other...

• Firth-adjusted GLM logit regression and confidence intervals

  Goodmorning,I ran a logistic regression model, through a GLM with binomial distribution and logit link function, with Firth adjustment as I got a warning on quasi-separation of data.I need to assess if my variable of interest (CHIP) is associated to the outcome (I have a binary response variable), in a model adjusted for other covariates.Now, I run the model, and I get a parameter estimate with a ...

• Nominal logistic vs GLM with binomial distribution and logit function

  Good morning everyone,I would like to get an answer from you, as to not misinterpret my results. I need to perform a multivariate analysis, assessing if the variables can predict the outcome cancer, so a binary response variable (0/1). With a dichotomous Y and multiple predictors in my model, I first tried using a nominal logistic regression, but in that case I got “unstable” estimates, therefore ...
