Levelwise DS证据频率

描述----------Description----------
Given a sample XX of polygonal fuzzy numbers and an interval IV the levelwise Dempster-Shafer frequency of the interval is calculated, i.e. for the chosen number nl of equidistant alpha-cuts it is checked how many of the elements of the sample have an alpha-cut that is contained in the interval (lower frequency) and how many have an alpha-cut hitting the interval (upper frequency). These family of intervals is afterwards aggregated to another polygonal fuzzy number with the corresponding number of alpha-cuts, which is returned. For details see [1] below. Preliminary the input data is tested for the correct format using the checking function.
给定的样本XX的折线模糊数和区间IV的levelwise DS证据频率的间隔的计算方法,即所选择的nl等距离的α-削减它被选中有多少样品的元素中所包含的的时间间隔(较低的频率)和多少有一个α-切割击中的时间间隔(上部频率)的α-切割。这些家庭的间隔后,汇总与相应数量的α-切口,则返回到另一个多边形模糊数。有关详细信息,请参阅[1]。初步测试输入的数据是正确的格式,使用checking函数。
用法----------Usage----------
DSfrequency(XX, IV = c(0, 1), pic = 1, nl = 101)
参数----------Arguments----------
参数:XX
...list of polygonal fuzzy numbers (the functions implicitly checks the conditions)
...折线模糊数列表(隐式的功能检查的条件)
参数:IV
...numeric vector of length two, by default IV=c(0,1)
数字矢量的长度为2,默认情况下,IV= C(0,1)
参数:pic
...numeric, in case pic=1 the frequency is plotted, otherwise no plot is produced
...数字的情况下pic= 1的频率绘制,否则没有图的生产
参数:nl
...number of equidistant alpha-levels, by default nl=101
...等距离的α-水平,默认情况下,nl= 101

值----------Value----------
Given correct input data, the function returns the levelwise Dempster-Shafer frequency of the chosen interval (again in the correct form of a polygonal fuzzy number).
正确的输入数据,函数返回levelwise的DS证据所选择的时间间隔(再次折线模糊数的正确形式)的频率。
