fill_complementary_probs: Fill Complementary Probabilities

In n8thangreen/CEdecisiontree: Cost-effectiveness decision tree analysis

Fill Complementary Probabilities

Description

Only one of each pair of branches is assigned a probability and then the other event probability is filled-in afterwards. This is good because specify fewer input values and if sampling probabilities we don't know the complementary probability.

Usage

fill_complementary_probs(dat_long)

Arguments

dat_long

Long format data frame with from, to, prob, vals columns.

Details

Only works for binary trees or when one of n is missing.

Value

Long format tree object

Examples

dat <- tibble::tribble(~from, ~to, ~prob, ~vals,
                       1,  2,  NA,    10,
                       1,  3,  0.8,    1,
                       2,  4,  0.2,   10,
                       2,  5,  NA,     1,
                       3,  6,  0.2,   10,
                       3,  7,  0.8,    1)
fill_complementary_probs(dat)
