Compute confidence intervals for the ratio (theta1/theta0) of two parameters based on point estimates and confidence intervals for the two parameters, theta1 and theta0.
1 | MOVERR(theta0, ci0, theta1, ci1, alternative = "two.sided")
|
theta0 |
a single numeric vale, the point estimate for the parameter to appear in the denominator |
ci0 |
vector with two numeric values, the lower and upper confidence limits for the parameter to appear in the denominator |
theta1 |
a single numeric vale, the point estimate for the parameter to appear in the numerator |
ci1 |
vector with two numeric values, the lower and upper confidence limits for the parameter to appear in the numerator |
alternative |
a character string, |
This function implements Eq. (9) in Donner and Zou (2012), for computing confidence intervals for a ratio of two parameters, when their estimators are uncorrelated.
a list with elements
conf.int |
numeric, the lower and upper confidence limits for the ratio |
estimate |
the point estimate for the ratio |
and the input estimates and confidence limits
