<--- Enter time (t) and survival rates (s) one per line as t,s
  <--- Enter time x (tx)
  <--- Enter time x + n (tx + n)

How does the Survival Rates Calculator work?
Free Survival Rates Calculator - Given a set of times and survival population counts, the calculator will determine the following:
Survival Population lx
Mortality Population dx
Survival Probability px
Mortality Probability qx
In addition, the calculator will determine the probability of survival from tx to tx + n
This calculator has 2 inputs.

What 1 formula is used for the Survival Rates Calculator?

dx = lx - lx + 1
px = lx + 1/ lx
qx = 1 - px

What 4 concepts are covered in the Survival Rates Calculator?
a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of time.
the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes
survival rates
a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis
