mhor {epicalc} | R Documentation |
Mantel-Haenszel odds ratio calculation and graphing from a stratified case-control study
mhor(..., mhtable = NULL, decimal=2, graph = TRUE, design = "cohort")
... |
Three variables viz. 'outcome', 'exposure' and 'stratification'. |
mhtable |
a 2-by-2-by-s table, where s (strata) is more than one |
decimal |
number of decimal places displayed |
graph |
If TRUE (default), produces an odds ratio plot |
design |
Specification for graph; can be "case control","case-control", "cohort" or "prospective" |
'mhor' computes stratum-specific odds ratios and 95 percent confidence intervals and the Mantel-Haenszel odds ratio and chi-squared test is given as well as the homogeneity test. A stratified odds ratio graph is displayed.
