bg.mcmc(MBCB)
bg.mcmc()所属R语言包:MBCB
MBCB - Bayesian Background Correction for Illumina Beadarray
MBCB - 贝叶斯Illumina的Beadarray的背景校正
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This function provides the means of using only the MCMC (Bayesian) background correction method for the Illumina platform.<br>
此功能提供了利用Illumina平台的MCMC(贝叶斯)背景校正方法的手段。参考
用法----------Usage----------
bg.mcmc(iter=500, burn=200)
参数----------Arguments----------
参数:iter
The iteration count for the Baysian correction.
为Baysian修正迭代计数。
参数:burn
The number of iterations to burn for the Bayesian correction.
贝叶斯校正迭代次数烧。
值----------Value----------
This function returns an array of alpha, mu, and sigma values representing the values computed during the mcmc trial.
这个函数返回一个α,亩,和sigma值代表在MCMC试验计算的值的数组。
注意----------Note----------
This function makes use of two global variables. It will expect obsbead and obsnc are both established prior to calling this function. Obviously, this is not ideal, but R's pass-by-value functionality hindered the ability to pass these matrices as parameters. Using global variables increases performance substantially.
此功能使用两个全局变量。它会期望obsbead和obsnc都成立之前,调用这个函数。显然,这是不理想,但R的价值传递的功能,阻碍了能力作为参数传递这些矩阵。使用全局变量的大幅提高性能。

# Use of global variables is obviously not ideal, but with R's pass-by-value [使用全局变量显然是不理想,但与R的价值传递]
# setup, we quickly run out of memory without using them on such large [设置,我们快速运行的内存,而无需使用他们如此大的]
# arrays[阵列]
#all of the signals from sample #2[所有的信号从样品#2]
obsbead <<- expressionSignal[,2]
#the negative control values for this sample[此范例为阴性对照值]
obsnc <<- negativeControl[,2]
#compute the alpha, mu, and sigma values[计算α,亩,和sigma值]
