Mitigated fraction — MFr • MF

Mitigated fraction comparing treatment to control.

Usage

MFr(formula, data, compare = c("con", "vac"))

Arguments

formula: Formula of the form y ~ x, where y is a continuous response and x is a factor with two levels
data: Data frame
compare: Text vector stating the factor levels – compare[1] is the control or reference group to which compare[2] is compared

Value

The estimated mitigated fraction.

Details

The mitigated fraction is an estimator that quantifies an intervention's effect on reducing the severity of a condition. Since its units are on the probability scale, it is often a good idea to accompany it with an estimator on the original scale of measurement.
