Baseline Quantification
Use this parameter to specify the statistics for quantifying the baseline across columns in the Input SAS Data Set (or the specified Baseline Reference SAS Data Set) for measurements with the same rank.
Statistics for quantifying the baseline are described in the table below:
|
Statistic |
Description |
|
Geometric Mean |
Constructs the baseline using the geometric mean across all of the data columns. This option should be selected for non-log transformed count data. |
|
Arithmetic Mean |
Constructs the baseline using the arithmetic mean across all of the data columns. This is the default option of quantile normalization. |
|
Median |
Constructs the baseline using the median across all of the data columns. This option should be selected for count data1. |
|
Upper Quartile |
Constructs the baseline using the upper quartile across all of the data columns. This option should be selected for count data. |
