These convenience functions make it easier to compute transition probabilities from incidence rates, OR, RR, or probabilities estimated on a different timeframe.
rescale_prob(p, to = 1, from = 1)prob_to_prob(...)
rate_to_prob(r, to = 1, per = 1)
or_to_prob(or, p)
rr_to_prob(rr, p)
A probability.
Probability.
Compute probability for that timeframe.
Timeframe of the original probability.
For deprecated functions.
Rate.
Number of person-time corresponding to the rate.
Odds ratio.
Relative risk.
# convert 5-year probability
# to 1-year probability
rescale_prob(p = .65, from = 5)
# convert 1-year probability
# to 1-month probability
rescale_prob(p = .5, to = 1/12)
# convert rate per 1000 PY
# to 5-year probability
rate_to_prob(r = 162, per = 1000, to = 5)
# convert OR to probability
or_to_prob(or = 1.9, p = .51)
# convert RR to probability
