restrict_by_query

Reduce nodal types using statement

internal

Users can declare binary causal models, update beliefs about causal types given data and calculate arbitrary estimands. Model definition makes use of 'dagitty' functionality. Updating is implemented in 'stan'. The approach used in 'CausalQueries' is a generalization of the 'biqq' models described in "Mixing Methods: A Bayesian Approach" (Humphreys and Jacobs, 2015, <DOI:10.1017/S0003055415000453>). The conceptual extension makes use of work on probabilistic causal models described in Pearl's Causality (Pearl, 2009, <DOI:10.1017/CBO9780511803161>).

restrict_by_query function

<dl><dt>model</dt>
<dd>a model created by make_model()</dd>
<dt>statement</dt>
<dd>a list of character vectors specifying nodal types to be
removed from the model. Use <code>get_nodal_types</code> to see syntax.</dd>
<dt>join_by</dt>
<dd>A string or a list of strings. The logical operator joining
expanded types when <code>statement</code> contains wildcard (<code>.</code>).
Can take values <code>'&amp;'</code> (logical AND) or <code>'|'</code> (logical OR).
When restriction contains wildcard (<code>.</code>) and <code>join_by</code> is not
specified, it defaults to <code>'|'</code>, otherwise it defaults to <code>NULL</code>.</dd>
<dt>given</dt>
<dd>A character vector or list of character vectors specifying
nodes on which the parameter set to be restricted depends. <code>given</code>
must either be NULL or of the same length as <code>statement</code>. When mixing
statements that are further restricted by <code>given</code> and ones that are
not, statements without <code>given</code> restrictions should have <code>given</code>
specified as one of <code>NULL</code>, <code>NA</code>, <code>""</code> or <code>" "</code>.</dd>
<dt>keep</dt>
<dd>Logical. If `FALSE`, removes and if `TRUE` keeps only
causal types specified by <code>restriction</code>.</dd></dl>
