Conditional and/or Marginal Probabilities
Description
Add conditional and/or marginal probabilities to a two-way contingency table.
Usage
addProbs(A, margin = seq_len(nd), fmt = "%d (%.1f%%)")
Arguments
A |
matrix of typeof integer, two-dimensional contingency table. See addmargins |
margin |
integer scalar or vector, see addmargins |
fmt |
character scalar,
C-style string format with a |
Details
Function addProbs provides the joint, marginal (using margin = 1:2
)
and conditional (using margin = 1L
or margin = 2L
)
probabilities of a two-dimensional contingency table.
Value
Function addProbs returns an 'addProbs'
object, which inherits from table and noquote.
Note
margin.table (which is to be renamed as marginSums) is much slower than colSums.
The use of argument margin
is
the same as addmargins,
and different from proportions!
