summary.admix_model

Summarizes the information related to the known component of the two-component mixture.
An admixture model has probability density function (pdf) l_i such that:
l_i = p_i * f_i + (1-p_i) * g_i, with g_i the known component density.
The unknown quantities are therefore p_i and f_i.

Implements techniques to estimate the unknown quantities
related to two-component admixture models, where the two components
can belong to any distribution (note that in the case of multinomial
mixtures, the two components must belong to the same family).
Estimation methods depend on the assumptions made on the unknown
component density; see Bordes and Vandekerkhove (2010)
<doi:10.3103/S1066530710010023>, Patra and Sen (2016)
<doi:10.1111/rssb.12148>, and Milhaud, Pommeret, Salhi, Vandekerkhove
(2024) <doi:10.3150/23-BEJ1593>. In practice, one can estimate both
the mixture weight and the unknown component density in a wide variety
of frameworks. On top of that, hypothesis tests can be performed in
one and two-sample contexts to test the unknown component density (see
Milhaud, Pommeret, Salhi and Vandekerkhove (2022)
<doi:10.1016/j.jspi.2021.05.010>, and Milhaud, Pommeret, Salhi,
Vandekerkhove (2024) <doi:10.3150/23-BEJ1593>). Finally, clustering of
unknown mixture components is also feasible in a K-sample setting (see
Milhaud, Pommeret, Salhi, Vandekerkhove (2024)
<https://jmlr.org/papers/v25/23-0914.html>).
