Compute the (traditional) confidence interval

computeTraditionalCi computes the traditional confidence interval based on the log of the relative risk and the standard error of the log of the relative risk.

computeTraditionalCi(logRr, seLogRr, ciWidth = 0.95)

Arguments

logRr

A numeric vector of one or more effect estimates on the log scale

seLogRr

The standard error of the log of the effect estimates. Hint: often the standard error = (log(<lower bound 95 percent confidence interval>) - log(<effect estimate>))/qnorm(0.025)

ciWidth

The width of the confidence interval. Typically this would be .95, for the 95 percent confidence interval.

Value

The point estimate and confidence interval

Examples

data(sccs)
positive <- sccs[sccs$groundTruth == 1, ]
computeTraditionalCi(positive$logRr, positive$seLogRr)
