Exercise

# Test for differential expression between 2 groups

Now that you have an ExpressionSet object and a design matrix, you can fit and test your model with limma.

Instructions

**100 XP**

The ExpressionSet object `eset`

with the leukemia data and the design matrix you just created (`design`

) have been loaded in your workspace.

Fit the model coefficients with

`lmFit`

.Calculate the t-statistics with

`eBayes`

.Summarize the results with

`decideTests`

.Since it doesn't make sense to test the intercept term, specify the coefficient

`"Diseasestable"`

when running`decideTests`

.
