加速失效时间模型(Accelerated Failure Time Model, AFT)是生存分析中的一种参数/半参数模型,用于研究协变量对事件发生时间的加速或延缓效应。其核心假设是:协变量通过线性关系改变生存时间的对数尺度,即: ln(T) = βX + ε 其中, T为生存时间, X为协变量, β为回归系数, ε为服从特定分布的误差项(如极值分...
缺失值在很对场景都会出现,即数据可能由于某种原因导致的不存在或者不完整,在R中缺失值的符号为NA(not variable,不可用),不管是字符型还是数值型,缺失值都表示为NA。 4.2.1 缺失值的判断 ()函数来进行缺失值的检测。该函数可以作用于任何一个对象上,返回一个相同大小的对象,若某个元素是缺失值,则对应位置返回...

Ashingleis a generalization of a factor to a continuous variable。A shingle consists of a numeric vector and a set of intervals。The intervals are allowed to overlap (much likeroof shingles; hence the name "shingles")。Shingles在lattice包中被广泛使用。they allow you to easily use a continuous...
