译者:生物统计家园网 机器人LoveR
描述----------Description----------
Monte Carlo test of spatial segregation in a multivariate point process by simulating data from random re-labelling of the categorical marks.
蒙特卡罗随机重新分类标志标签,通过模拟数据测试的空间隔离在一个多元点过程。
用法----------Usage----------
mcseg.test(pts, marks, h, stpts = NULL, ntest = 100,
proc = TRUE)
参数----------Arguments----------
参数:pts
matrix containing the x,y-coordinates of the data point locations.
基质中含有x,y坐标的数据点的位置。
参数:marks
numeric/character vector of the marked type labels of the point pattern.
数字/字符向量类型标签的点模式的显着。
参数:h
numeric vector of the bandwidths at which to calculate the cross-validated likelihood function.
数值向量计算的交叉验证的似然函数的带宽。
参数:stpts
matrix containing the x,y-coordinates of the locations at which to implement the pointwise segregation test, with default NULL not to do the pointwise segregation test.
基质中含有x,y坐标的位置,在实施逐点的隔离测试,默认情况下,NULL没有这样做的逐点的隔离测试。
参数:ntest
integer with default 100, number of simulations for the Monte Carlo test
整数默认为100,蒙地卡罗模拟测试
参数:proc
logical with default TRUE to print the processing messages.
默认情况下,逻辑与TRUE要打印的消息进行处理。
Details
详细信息----------Details----------
The null hypothesis is that the estimated risk surface is spatially constant, i.e., the type-specific probabilities are p_k(x)=p_k, for all k, see phat. Each Monte Carlo simulation is done by relabeling the data categorical marks at random whilst preserving the observed number of cases of each type.
零假设是估计的风险面是空间不变,即特定类型的概率是p_k(x)=p_k,为所有的k信息,请参阅phat。蒙特卡罗模拟是通过重新贴标签的数据分类标记,随机,同时保留所观察到的每种类型的情况数量。
The segregation test can also be done pointwise, usually at a fine grid of points, to mark the areas where the estimated type-specific probabilities are significantly greater or smaller than the spatial average.
隔离测试也可以逐点,通常在细网格点,估计特定类型的概率显着大于或小于空间平均标记的区域。
值----------Value----------
A list with components
