adj_inv_sinh_ci_or.RdComputes the adjusted inverse hyperbolic sine confidence interval for the odds ratio.
adj_inv_sinh_ci_or(data, x, y, psi1 = 0.6, psi2 = 0.4, alpha = 0.05)
| data | tbl. Input data |
|---|---|
| x, y | character. Variable names |
| psi1, psi2 | double. Pseudo-frequencies (both should be > 0), Default: 0.6, 0.4 |
| alpha | double. The nominal level, Default: 0.05 |
tbl. Data frame with odds ratio and CIs
Procedure as described in Fagerland & Newcombe (2013) and Fagerland, Lydersen, & Laake (2017).
The function is an adaptation of the Matlab script provided by Fagerland et
al. (2017) on the book's
