Quantile Normalization
The Quantile Normalization process normalizes data by aligning ranked columns, computing their mean , and then replacing the original data with the average quantiles . It guarantees identical marginal univariate densities of each column.
What do I need?
Two data sets are required to run this process.
The first data set, the Input Data Set , contains all of the numeric data to be analyzed. This data set must be in the tall format where each sample corresponds to one row and each column corresponds to a separate experimental condition or array.
The drosophilaaging.sas7bdat data set, shown below, is a normalized data set derived from the Drosophila Aging experiment described in Sample Case Studies . It has 49 columns and 100 rows corresponding to 49 arrays and 100 individual probes , respectively.
The second data set is the Experimental Design Data Set (EDDS) . This required data set tells how the experiment was performed, providing information about the columns in the input data set. Note that one column in the EDDS must be named ColumnName and the values contained in this column must exactly match the column names in the input data set.
The drosophilaaging_exp.sas7bdat EDDS, is shown below. Note that the ColumnName column lists the column names in the input data set. The Array column corresponds to an index variable . Note the variables describing experimental conditions.
The drosophilaaging.sas7bdat and drosophilaaging_exp.sas7bdat data sets are included in the Sample Data folder.
