Expression Utilities

Click on a button corresponding to an expression utility . Refer to the table below for guidance.

Process	Choose this process for...
Combine Experiments	Combining experiments by merging multiple tall data sets and appending their corresponding Experimental Design Data Set (EDDS) s together to create: • a single tall data set, and • a single EDDS
Split Experiment	Dividing an experiment into separate experiments either randomly or according to variables in the Experimental Design Data Set (EDDS) , with each split creating: • separate tall data sets, and • separate EDDSs
Mixed Model Power	Determining the sample size of an experiment needed to achieve a desired statistical power , or determining the statistical power of an experiment given a specified sample size Tip : This process is typically used before a full experiment is run. It is helpful to run a pilot study in order to determine reasonable values for variance components.
