Converting log hazard function to survival probability
I wanted to estimate survival probabilities over time based on knowing only the $\log({\rm hazard})$ which takes the form of powers of $t$. … Essentially I am looking to obtain a formula which predicts survival over time based on this hazard. Can anyone give me a heads-up about how I proceed with this? …

log hazard function in R
I'm trying to write out the log hazard function of the lognormal distribution and use this in R. … Using the survival function:
and the hazard function:
I have the following for the log(hazard):
log(hazard) = $-\log(2\pi)/2-\log(\sigma)-\log(t) - ((\log(t)-\mu)^2)/(2\sigma^2) - \log(1-\phi((\ …
