WebThe C-index represents the global assessment of the model discrimination power: this is the model’s ability to correctly provide a reliable ranking of the survival times based on the individual risk scores. In general, when the C-index is close to 1, the model has an almost perfect discriminatory power; but if it is close to 0.5, it has no ability to discriminate … Web6 Jul 2024 · 正态分布. 若随机变量x服从有个数学期望为μ,方差为σ 2 的正态分布，记为 N(μ,σ). 其中期望值决定密度函数的位置，标准差决定分布的幅度，当 υ=0，σ=1 时的正态分布是标准正态分布. 判断方法有画图/k-s检验

Web23 Feb 2024 · A histogram is a plot of the frequency distribution of numeric array by splitting it to small equal-sized bins. If you want to mathemetically split a given array to bins and frequencies, use the numpy histogram() method and pretty print it like below. import numpy as np x = np.random.randint(low=0, high=100, size=100) # Compute frequency and ...
