译者:生物统计家园网 机器人LoveR
描述----------Description----------
rguman generates random draws from a dyad census-conditioned uniform random graph distribution.
rguman生成随机抽取的二分体人口普查空调,均匀分布的随机图分布。
用法----------Usage----------
rguman(n, nv, mut = 0.25, asym = 0.5, null = 0.25,
method = c("probability", "exact"), return.as.edgelist = FALSE)
参数----------Arguments----------
参数:n
the number of graphs to generate.
的图形的数目来生成。
参数:nv
the size of the vertex set (|V(G)|) for the random graphs.
的顶点集合的大小(|V(G)|)的随机图形。
参数:mut
if method=="probability", the probability of obtaining a mutual dyad; otherwise, the number of mutual dyads.
如果method=="probability",取得相互对子的概率;否则,相互二价基的数目。
参数:asym
if method=="probability", the probability of obtaining an asymmetric dyad; otherwise, the number of asymmetric dyads.
如果method=="probability",得到不对称的对子的概率;否则,不对称的二价基的数目。
参数:null
if method=="probability", the probability of obtaining a null dyad; otherwise, the number of null dyads.
如果method=="probability",获得一个空的概率对子,否则,空二人组合的数量。
参数:method
the generation method to use. "probability" results in a multinomial dyad distribution (conditional on the underlying rates), while "exact" results in a uniform draw conditional on the exact dyad distribution.
的生成的方法来使用。 "probability"结果对子分布在多项条件的基本税率,而"exact"有条件的确切对子分布在一个统一的抽奖结果。
参数:return.as.edgelist
logical; should the resulting graphs be returned in edgelist form?
逻辑,生成的图表在EdgeList,在该列表的形式返回?

详细信息----------Details----------
A simple generalization of the Erdos-Renyi family, the U|MAN distributions are uniform on the set of graphs, conditional on order (size) and the dyad census. As with the E-R case, there are two U|MAN variants. The first (corresponding to method=="probability") takes dyad states as independent multinomials with parameters m (for mutuals), a (for asymmetrics), and n (for nulls). The resulting pmf is then
一个简单的概括,鄂尔多斯仁义家庭,U |的MAN分布均匀的一套图,有条件的顺序(大小)和对子人口普查的。与雌激素受体的情况下,有两个U |城域网变种。第一个(对应的method=="probability")独立多项式的对子状态与参数m(互助),a(为asymmetrics),和n(空值)。由此产生的PMF是

The second U|MAN variant is selected by method=="exact", and places equal mass on all graphs having the specified (exact) dyad census. The corresponding pmf is
第二个U | MAN变体选择method=="exact",并将质量相等的所有图形指定的(精确)对子人口普查。相应的PMF是

U|MAN graphs provide a natural baseline model for networks which are constrained by size, density, and reciprocity. In this way, they provide a bridge between edgewise models (e.g., the E-R family) and models with higher order dependence (e.g., the Markov graphs).
U |文图提供了一个天然的基线网络模型的大小,密度和互惠的限制。这样一来,他们之间的桥梁,沿边模式(例如,ER系列)和模式具有较高的依赖性(例如,马氏图)。
