Description
The nose package consists of a collection of three
functions for classifying sparseness in typical 2 x 2 data sets
with at least one cell should have zero count. These functions
are based on the three widely applied summary measures for 2 x
2 categorical data viz, Risk Difference (RD), Relative Risk
(RR), Odds Ratio (OR). This package helps to identify suitable
continuity correction for zero cells when a multi centre
analysis or a meta analysis is carried out. Further, it can be
considered as a tool for sensitivity analysis for adding a
continuity correction and to identify the presence of Simpson's
paradox.
