Independence table
Estimates the expected frequencies from an m-way table under the null hypotheses of independence.
indTab(
x,
margin = c("gmean_sum", "sum"),
frequency = c("relative", "absolute"),
pTabMethod = c("dirichlet", "half", "classical")
)x |
an object of class table |
margin |
determines how the margins of the table should be estimated (default via geometric mean margins) |
frequency |
indicates whether absolute or relative frequencies should be computed. |
pTabMethod |
to estimate the propability table. Default is ‘dirichlet’. Other available methods:
‘classical’ that is function |
Because of the compositional nature of probability tables, the independence tables should be estimated using geometric marginals.
The independence table(s) with either relative or absolute frequencies.
