aux_validateRows

Validates and expands rows if necessary.

Choice models are a widely used technique across numerous scientific disciplines. The Apollo package is a very flexible tool for the estimation and application
of choice models in R. Users are able to write their own
model functions or use a mix of already available ones. Random heterogeneity,
both continuous and discrete and at the level of individuals and
choices, can be incorporated for all models. There is support for both standalone
models and hybrid model structures. Both classical
and Bayesian estimation is available, and multiple discrete
continuous models are covered in addition to discrete choice.
Multi-threading processing is supported for estimation and a large
number of pre and post-estimation routines, including for computing posterior
(individual-level) distributions are available.

models see Train, K. (2009) <isbn:978-0-521-74738-7> and Hess,
S. & Daly, A.J. (2014) <isbn:978-1-781-00314-5> for an overview
of the field.

aux_validateRows function

<dl><dt>rows</dt>
<dd>Boolean vector. Consideration of which rows to include. Length equal to the number of observations (nObs), with entries equal to TRUE for rows to include, and FALSE for rows to exclude. Default is <code>"all"</code>, equivalent to <code>rep(TRUE, nObs)</code>. Set to <code>"all"</code> by default if omitted.</dd>
<dt>componentName</dt>
<dd>Character. Name given to model component. If not provided by the user, Apollo will set the name automatically according to the element in <code>P</code> to which the function output is directed.</dd>
<dt>apollo_inputs</dt>
<dd>List grouping most common inputs. Created by function apollo_validateInputs.</dd></dl>
