详细信息----------Details----------
This is a generic function for computing the intensity of a spatial dataset or spatial point process model. There are methods for point patterns (objects of class "ppp") and fitted point process models (objects of class "ppm").
这是一个通用的功能强度的空间数据集或空间点过程模型计算。有点模式(对象类"ppp"),并配备点过程模型(对象类"ppm")的方法。
The empirical intensity of a dataset is the average density (the average amount of "stuff" per unit area or volume). The empirical intensity of a point pattern is computed by the method intensity.ppp.
经验强度的数据集的平均密度(平均每单位面积或体积的东西)。点模式的实证强度的计算方法intensity.ppp。
The theoretical intensity of a stochastic model is the expected density (expected amount of "stuff" per unit area or volume). The theoretical intensity of a fitted point process model is computed by the method intensity.ppm.
的随机模型的理论强度是预期的密度(预期量的每单位面积或体积的东西)。的拟合点过程模型计算的理论强度的方法intensity.ppm。
值----------Value----------
Usually a numeric value or vector.
通常一个数值或向量。
