准确显示癌症的特定存活时间(Kaplan Meier在生命线中)

Question

kmf.survival_function_ (LifeLines Package)

向我展示不同时间(0，4，6.128个月)我的队列的癌症特异性生存(CSS)。CSS如何显示在确切的120个月？

Answer 1

survival_function_at_times()方法将为您提供该值。下面是一个示例数据集示例：

from lifelines import KaplanMeierFitter

from lifelines.datasets import load_waltons
data = load_waltons()

T = data['T']
E = data['E']

kmf = KaplanMeierFitter().fit(T, E, label='KaplanMeierFitter')

timeline = [10, 12, 14]  # insert 120 and/or any other values here

# directly compute the survival function, returning a pandas Series
kmf.survival_function_at_times(timeline)

# 10    0.96921
# 12    0.96921
# 14    0.95069
# Name: KaplanMeierFitter, dtype: float64
