Description
A function for ploting the odds of being a case vs control and their effects on adjustments for confounders.
It may be useful in cases when it is envisaged that no confounders are expected.
It automatically plots the values of Z for the common experimental designs (e.g. 1:1, 1:3 and 1:4). You input
alarge number of hypothetical ratios of proportions of cases to controls. It uses another function (ztwo), which
computes the Z values.
Usage
1
ZvaluescasesVcontrolsPlots(probs)
Arguments
probs
A vector of a large number of hypothetical ratios of proportions of cases to controls.
Value
It returns a pdf plot of the odds of being a case vs control and their effects on adjustments for confounders.
