Details
详细信息----------Details----------
cutoff generates a valid object of class "cutoff". As function slot fct may only have a formal argument data, the other arguments to determine the cutoff value, i.e. norm, QF, nsim, cutoff.quantile, nsim have to enter the scope of this function by lexical scoping; now cutoff.quantile, norm, QF are to be taken from the calling environment (not from the defining one), so we have delay evaluation of the function body, which is why we assume it to be given wrapped into substitute resp. quote. body.fct0 is by default (i.e. if argument body.fct0 is missing) set to quote(quantile(slot(norm,"fct")(data), cutoff.quantile)), internally, i.e.; to an empirical quantile of the corresponding norms.<br>
cutoff产生一个有效的对象类"cutoff"。功能插槽fct可能只有一个正式的参数data，其他参数确定的临界值，即norm，QF，nsim，cutoff.quantile，nsim进入此功能的范围由词法范围;现在cutoff.quantile，norm，QF要调用环境中（而不是从定义一个），所以我们必须在函数体的延迟评价，这就是为什么我们认为它被包裹成substituteRESP。 quote。 body.fct0在默认情况下（即参数body.fct0丢失）设置为quote(quantile(slot(norm,"fct")(data), cutoff.quantile))，内部，即经验分位数相应的规范。<BR>
cutoff.sememp() is a helper function generating the theoretical (asymptotic) quantile of (the square root of) a corresponding quadratic form, assuming multivariate normality; to determine this quantile nsim simulations are used.<br>
cutoff.sememp()是一个辅助函数生成的理论（渐进）位数的平方根（）对应的二次型，假定多元常态，以确定这位数nsim模拟。<BR>
cutoff.chisq() is a helper function generating the theoretical (asymptotic) quantile of (the square root of) a (self-standardized) quadratic form, assuming multivariate normality; i.e.; a corresponding quantile of a Chi-Square distribution.
cutoff.chisq()是一个辅助函数生成的理论（渐进）位数（平方根）（标准化）二次型，假定多元常态，即一个相应的卡方分布的分位数。
值----------Value----------
Object of class "cutoff".
对象类"cutoff"。
