Determining a Detectable Threshold of Signal Intensity in cDNA Microarray Based on Accumulated Distribution

In microarray data mining, one of the key problems is howto handle weak signals. Based on a bent piecewise linearaccumulated distribution generally found in themicroarray data, a new detectable threshold findingmethod is proposed to filter genes with unreliableinformation in this paper. More reliable and reproducibledata is produced for the subsequent data mining.Keywords:
