Split Plots

Chapter 19 Split-Plot Designs - Purdue University

experimenter uses a split-plot design as follows: 1. To divide each block into three equal sized plots ( whole plots ), and each plot is assigned a variety of oat according to a randomized block design. 2. Each whole plot is divided into 4 plots ( split-plots) and the four levels of manure are randomly assigned to the 4 split-plots.

The HPSPLIT Procedure - SAS

At each step of the recursion, the parent node is split into child nodes through selection of a predictor variable and a split value that minimize the variability in the response across the child ... plots for cost-complexity analysis, and plots of ROC curves computes statistics for assessing model fit, including model-based (resubstitution ...

The Analysis of Split-Plot Experiments

whole plots. The reason is that in this experimental design we have randomized the levels of A on the whole plots so that an experimental unit corresponding to A is a whole plot. Based on the additive split-plot model given by (7-2) a test for an effect of the whole plot factor A, that is the hypothesis H0: a(a 1) = = a(a k), is equivalent to ...

What is FT IR? - Northwestern University

An interferometer utilizes a beamsplitter to split the incoming infrared beam into two optical beams. One beam reflects off of a flat mirror which is fixed in place. ... present an infrared spectrum, which plots adsorbance (or transmittance) versus wavenumber. When an interferogram is Fourier transformed, a single beam spectrum is generated. ...

Split Plots - UMN Statistics

A split split plot has three sizes of units: whole plots that are made up of split plots which are made up of split split plots. Two levels of nesting in the unit structure: split split plots nest into split plots, and split plots nest into whole plots. You need at least three factors: a whole plot treatment factor, a

FRACTIONAL FACTORIAL DESIGNS Sometimes, there aren’t enough resources to run a Full Factorial Design. Instead, you can run a fraction of the total # of treatments. 2k-p kdesign = k factors, each with 2 levels, but run only 2-p treatments (as opposed to 2k) 24-1 design = 4 factors, but run only 23 = 8 treatments (instead of 16) 8/16 = 1/2 design known as a “½ replicate” or …
