6. Survival analysis, Expectation-Maximisation Flashcards
1
Q
What does f_i, s_i, h_i and S_j_i tell us? Write the formulas, in discrete case
A
f_i = prob of dying at age i
S_i = is the prob of surviving past age i -1
2
Q
How would we do this in a continuous case?
A
3
Q
What is censored data?
A
4
Q
What is hazard ratio?
A
The hazard ratio (HR) is the ratio of the hazard rates corresponding to the
conditions characterised by two distinct levels of a treatment variable of interest.
5
Q
Explain why a log rank test can be needed and what it is
A
It is useful for data that is censored and a non parametric test to see outcomes on two different test groups.
