Figure 4From: An optimization framework for unsupervised identification of rare copy number variation from SNP array dataDiscordance rate as a function of call frequency strata. The figure shows how the discordance rates behave as a function of the sample frequency threshold. Note that discordance rate is plotted cumulatively - that is, the value on the y-axis is the average discordance rate for CNVs with frequencies, at most, the corresponding value on the x-axis. The discordance value at the sample frequency threshold value t is calculated by finding the discordance rate across all CNVs with frequency at most t.Back to article page
