我有以下数据:

gasdfhourly[['Unit','Hourcount','Target']].head()

Out[377]:

Unit Hourcount Target

Date hour

2014-01-01 0 748.816493 1 0.0

1 759.759946 2 0.0

2 756.737007 3 0.0

3 761.075262 4 0.0

4 765.142517 5 0.0

我试着用考克斯博士的模型来适应它:

from lifelines import CoxPHFitter

cph = CoxPHFitter()

cph.fit(gasdfhourly, duration_col='Hourcount', event_col='Target', show_progress=False)

cph.print_summary()

X=gasdfhourly['Unit']

cph.predict_survival_function(X)

我得到以下错误:

Traceback (most recent call last):

cph.predict_survival_function(X)
