Computes the sample size required to estimate Yule's Q with desired
confidence interval precision. Set the Yule's Q planning value to the
smallest absolute value within a plausible range for a conservatively large
sample size.
Usage
size.ci.yule(alpha, p1, p2, Q, w)
Arguments
- alpha
alpha level for 1 - alpha confidence
- p1
planning value for row 1 marginal proportion
- p2
planning value for column 1 marginal proportion
- Q
planning value of Yule's Q
- w
desired confidence interval width
Value
Returns the required sample size
Examples
size.ci.yule(.05, .3, .2, .5, .4)
#> Sample size
