intercept()所属R语言包:segmented
Intercept estimates from segmented relationships
拦截估计分割的关系
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Computes the intercepts of each "segmented" relationship in the fitted model.
计算每个“分段”的关系拟合模型的截距。
用法----------Usage----------
intercept(ogg, parm, gap = TRUE, rev.sgn = FALSE, var.diff=FALSE)
参数----------Arguments----------
参数:ogg
an object of class "segmented", returned by any segmented method.
一个类的对象“分段”,返回的任何segmented方法。
参数:parm
the segmented variable whose intercepts have to be computed. If missing all the segmented variables in the model are considered.
分段变量,要计算其拦截。如果丢失了所有的分段的模型中的变量被认为。
参数:gap
logical. should the intercepts account for the (possible) gaps?
逻辑。的截距应占(可能的)差距?
参数:rev.sgn
vector of logicals. The length should be equal to the length of parm, but it is recycled otherwise. when TRUE it is assumed that the current parm is "minus" the actual segmented variable, therefore the sign is reversed before printing. This is useful when a null-constraint has been set on the last slope.
向量,逻辑值。长度应等于的长度parm,但它被回收,否则。当TRUE,假设当前parm是减去的实际分段变量,因此,该标志在打印前拨回。这是非常有用的,在过去的斜坡上设置了一个空的约束时。
参数:var.diff
Currently ignored as only point estimates are computed.
目前被忽略,因为只有点估计计算。
Details
详细信息----------Details----------
A broken-line relationship means that a regression equation exists in the intervals 'min(x) to psi1', 'psi1 to psi2', and so on. intercept computes point estimates of the intercepts of the different regression equations for each segmented relationship in the fitted model.
虚线关系的回归方程中存在的时间间隔min(x)到psi1,psi1到psi2,等等。 intercept计算点的拟合模型为每一个分割的关系在不同的回归方程的截距的估计。
值----------Value----------
intercept returns a list of one-column matrices. Each matrix represents a segmented relationship.
intercept返回一个列表的一列矩阵。每个矩阵代表一个分段的关系。
