elem_imset: Get a (semi-)elementary imset

In rje42/imset: Methods for imsets with mixed graphs

Get a (semi-)elementary imset

Description

Returns a semi-elementary imset u_{\langle A, B | C \rangle} (as defined in Studeny, 2005) given numeric arguments or a ci object.

Usage

elem_imset(...)

elem_imset.default(A, B, C = integer(0), n = max(c(A, B, C)), check = TRUE)

elem_imset.ci(ci, n)

sei2ci(imset)

ci2sei(ci, n = max(vars))

Arguments

A, B, C	disjoint subsets of 1,..,n
n	number of variables involved
check	logical: check entries are valid?
ci	object of class ci
imset	semi-elementary imset

Details

Returns an imset, a vector of length 2^n with all but four entries zero.

Functions

• elem_imset.default(): Method for integer vectors

• elem_imset.ci(): Method for ci object

• sei2ci():

• ci2sei(): convert conditional independence to semi-elementary imset
