EBAM基于重要性
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Determines the importance of interactions found by logic.bagging or logicFS by an Empirical Bayes Analysis of Microarrays (EBAM). Only available for the classification and the logistic regression approach of logic regression.
决定重要性logic.bagging或logicFS经验Bayes分析微阵列（EBAM）。发现的相互作用仅可用于分类和逻辑回归Logistic回归方法。
用法----------Usage----------
vim.ebam(object, data = NULL, cl = NULL, nameEBAM = NULL, ...)
参数----------Arguments----------
参数：object
either an object of class logicFS or the output of an application of logic.bagging with importance = TRUE.
无论是一个对象类logicFS或输出logic.bagging与importance = TRUE应用。
参数：data
a data frame or matrix consisting of 0's and 1's in which each column corresponds to one of the explanatory variables used in the original analysis with logic.bagging or logicFS, and each row corresponds to an observation. Must be specified if object is an object of class logicFS, or cl is specified. If object is an object of class logicBagg and neither data nor cl is specified, data and cl stored in object is used to compute the ChiSquare statistics. It is, however, highly recommended to use new data to test the interactions contained in object, as they have been found using the data stored in object, and it is very likely that most of them will show up as interesting if they are tested on the same data set.
一个数据框或矩阵组成的0和1的每列对应原来logic.bagging或logicFS分析中使用的解释变量之一，每行对应一个观察。必须指定object如果类logicFS或cl指定的对象。 object如果是一个类的对象logicBagg“既不data也cl指定，data和cl存储object中用于计算卡方统计。它是，但是，强烈建议使用新的data测试中包含的相互作用object，因为他们已经发现使用dataobject存储，它是很可能，他们大多会表现为有趣，如果他们相同的数据集上进行测试。
参数：cl
a numeric vector of 0's and 1's specifying the class labels of the observations in data. Must be specified either if object is an object of class logicFS, or if data is specified.
指定的0和1的数字向量的意见类的标签，在data。如果object类logicFS，或者data指定的对象，必须指定。
参数：nameEBAM
a character string. If specified, then the output of the EBAM analysis is stored under this name in the global environment.
一个字符串。如果指定的话，那么输出的EBAM分析这个名字在全球环境下储存。
参数：...
further arguments of ebam and cat.ebam. For details, see the help files of these functions from the package siggenes.

详情----------Details----------
For each interaction found by logic.bagging or logicFS, the posterior probability that this interaction is significant is computed using the Empirical Bayes Analysis of Microarrays (EBAM). These posterior probabilities are used as the EBAM based importances of the interactions.
每个交互对于logic.bagging或logicFS发现的，后验概率，这种互动是显着的使用经验Bayes分析微阵列（EBAM）计算。这些后验概率是基于重要性的相互作用EBAM的。
The test statistic underlying this EBAM analysis is Pearson's ChiSquare statistic. Currently, the value of this statistic is computed without continuity correction.
基本这EBAM分析测试统计，Pearson的卡方统计。目前，这个统计值计算不连续性校正。
Contrary to vim.logicFS (and vim.norm and vim.signperm), vim.ebam does neither take the logic regression models into acount nor uses the out-of-bag observations for computing the importances of the identified interactions. It "just" tests each of the found interactions on the whole data set by calculating Pearson's ChiSquare statistic for each of these interactions and performing an EBAM analysis. It is, therefore, highly recommended to use an independent data set for specifying the importances of these interactions with vim.ebam.
相反vim.logicFS（vim.norm和vim.signperm）vim.ebam，既不考虑acount逻辑回归模型，也没有使用计算的重要性袋意见确定的相互作用。它“只是”测试发现这些相互作用，通过计算Pearson的卡方统计和执行EBAM分析整个数据相互作用。因此，它高度建议使用指定vim.ebam这些相互作用的重要性，树立了一个独立的数据。
