Building Linear Mixed Models Using JMP® Pro 15
Presenter: Jian Cao
Using JMP Pro 15 to Handle Random and Fixed Effects, Repeated Measures, Random Coefficients and Variance Components
See how to:
- Analyze a wide variety of linear mixed models easily and effectively
- Analyze split-plot designs using an example that studies the effects of four process conditions on resistance in wafers
- Understand how fitting Standard Least Squares can lead to incorrect inferences
- See how JMP Pro 15 mixed model scripts are useful for split-plot designs
- Analyze Repeated Measures, using an example that accounts for correlation between observations, to effectively understand treatment effects
- Consider and compare alternative covariance structures and choose the best fit
- Perform Individual Growth Analysis using Random Coefficients and an example that seeks to determine if any of three treatments had an effect on a growth response
- Perform Variance Components Analysis using a measurement system study example
NOTE: Q&A is included at times 37:52 and 53:21.
Overview and Random Coefficients Models
See how to build a Random Coefficients Model to determine the effect of moisture on winter wheat. Learn how to use Profilers, Residual Plots, Covariance Matrices, marginal distributions and conditional distributions to understand the model. NOTE: This video was recorded before JMP Pro 15 was available.
Repeated Measures and Panel Data Models
See how to allow errors to be correlated by building a Repeated Measures model to evaluate the effect of a new drug on lowering cholesterol, and get tips and tricks for using this approach. The presenter builds a Panel Data Model that controls for unobserved individual homogeneity to determine if there is any wage gain associated with being a trade union member. NOTE: This video was recorded before JMP Pro 15 was available.
See how to build and compare several geospatial models to evaluate water movements at a potential waste management site. The presenter chooses this approach because the investigators want to determine if the geographic location of samples affects the samples in some way. NOTE: This video was recorded before JMP Pro 15 was available.
