  • Lack of fit test

    Hello everyone. I have a question related to DOE.
    When conducting a Lack of fit test, how should the F ratio be calculated? F=MS residual /MS pure eror  or  F=MS lack of fit/MS pure eror. The idea is to compare the model error with the experimental error..  Are the results obtained from the two formulas different? Which result is more reliable and when is it necessary to use each of the two formula...

  • Why does SLS (REML) give a different intercept than Python statsmodels for the same mixed model?

    I fitted: Y ~ A(Sum) + B(Sum) + C(Sum) + D(Sum) + Subject(&Random)   in both JMP SLS (REML) and Python statsmodels MixedLM (REML) on the same data (~14k obs, ~200 levels of A, sparse A×C cross-tabulation, ~120 random subjects). What I observe: All ~200 LS Means for factor A are shifted by a constant ~0.22 (JMP higher)Relative effects and rankings are identical (diff std < 0.001)LS Means f...

  • What is the best analysis to use for correlations between ''viscosity, ethanol, glycerol, sugar profile'' ?

    Hello, I am interested to understand if anyone has used specific analysis for correlation between viscosity, ethanol, glycerol and sugar profile. If you can recommend the right statistic analysis, will be amazing.

  • How to Look at Range Data High Medium Low

    Looking for the Best way to analysis Data when I have Ranges Upper, Mid and Lower for both Voltage and Freq. data.  See RED Columns.  Guess I could perform a Control Chart or Dist. but like to to see if their is a shift of this many Electrical Devices.   Any Suggestions?

  • Predicting degradation data

    What modeling approach can predict 24‑month concentration from previous degradation data with different initial values? There is degradation data measured over time (ex. up to 24 months) for several batches/samples.
    Each batch starts at a different initial concentration at release, and not all batches are measured at all time points (there are missing observations for later time points). All measur...

  • Hierarchical clustering platform color map columns

    I have a hierarchical cluster with ~ 2700 Y -rows and 100 columns of data. When complete I want to color map the clusters to two other columns in the data.    I can do so but then the questions start. 1.  One color map is to identify the rows of data by a type (in this case a tissue type).  That accurately displays as a color for each tissue but, how do I attach a legend to the visualization for t...

  • Cohen's d Effect Size from Mixed Model Output

    Hello, I am wondering how I can calculate a Cohen's d effect size from my mixed model output (attached), especially in the case of an interaction effect? I have seen some online resources saying to use the least squares mean difference divided by the model root mean square error in order to do so for main effects. However, when doing this, I sometimes get an effect size that appears inflated based...
