Exact_cond_midP_unspecific_ordering_rx2 {contingencytables} | R Documentation |
The exact conditional and mid-P tests for unspecific ordering. May also be used for 2xc tables, after flipping rows and columns (i.e. if n is a 2xc table, call this function with n' (the transpose of n) as the first argument).
Described in Chapter 5 "The Ordered rx2 Table"
Exact_cond_midP_unspecific_ordering_rx2(n, direction, statistic = "Pearson")
n |
the observed counts (an rx2 matrix) |
direction |
the direction of the success probabilities ("increasing" or "decreasing") |
statistic |
the Pearson test statistic ("Pearson") or the likelihood ratio test statistic ("LR"). Can also be used for cumulative ORs in 2xc tables with "PearsonCumOR" or "LRCumOR". |
An object of the contingencytables_result class,
basically a subclass of base::list()
. Use the utils::str()
function
to see the specific elements returned.
