Preprocessing

Prepare raw microarray data for analysis

Process microarray data using background adjustment, normalization, and expression filtering.

Functions

Normalization

`malowess`	Smooth microarray data using Lowess method
`exprprofrange`	Calculate range of gene expression profiles
`exprprofvar`	Calculate variance of gene expression profiles

Gene Filtering

`geneentropyfilter`	Remove genes with low entropy expression values
`genelowvalfilter`	Remove gene profiles with low absolute values
`generangefilter`	Remove gene profiles with small profile ranges
`genevarfilter`	Filter genes with small profile variance

Visualization
