Estimate the association parameter of
 Ali-Mikhail-Haq's bivariate
 distribution by maximum likelihood estimation.

biamhcop

An implementation of about 6 major classes of
statistical regression models. The central algorithm is
Fisher scoring and iterative reweighted least squares.
At the heart of this package are the vector generalized linear
and additive model (VGLM/VGAM) classes. VGLMs can be loosely
thought of as multivariate GLMs. VGAMs are data-driven
VGLMs that use smoothing. The book "Vector Generalized
Linear and Additive Models: With an Implementation in R"
(Yee, 2015) <DOI:10.1007/978-1-4939-2818-7> gives details of
the statistical framework and the package. Currently only
fixed-effects models are implemented. Many (100+) models and
distributions are estimated by maximum likelihood estimation
(MLE) or penalized MLE. The other classes are RR-VGLMs
(reduced-rank VGLMs), quadratic RR-VGLMs, doubly constrained
RR-VGLMs, quadratic RR-VGLMs, reduced-rank VGAMs,
RCIMs (row-column interaction models)---these classes perform
constrained and unconstrained quadratic ordination (CQO/UQO)
models in ecology, as well as constrained additive ordination
(CAO). Hauck-Donner effect detection is implemented.
Note that these functions are subject to change;
see the NEWS and ChangeLog files for latest changes.

Ali-Mikhail-Haq Distribution Family Function — biamhcop

<dl>

 <dt>lapar</dt>
<dd>Link function applied to the association parameter
 \(\alpha\), which is real
 and \(-1 &lt; \alpha &lt; 1\).
 See <code>Links</code> for more choices.

</dd>

 <dt>iapar</dt>
<dd>Numeric. Optional initial value for \(\alpha\).
 By default, an initial value is chosen internally.
 If a convergence failure occurs try assigning a different value.
 Assigning a value will override the argument <code>imethod</code>.

</dd>

 <dt>imethod</dt>
<dd>An integer with value <code>1</code> or <code>2</code> which
 specifies the initialization method. If failure to converge occurs
 try the other value, or else specify a value for <code>iapar</code>.

</dd>

 <dt>nsimEIM</dt>
