%description
Maximum likelihood estimation of component lifetime parameters from
system-level observations of k-out-of-n systems. Supports exponential and
Weibull component distributions under multiple observation schemes: Scheme
0 (system lifetime only), Scheme 1 (periodic inspection), and Scheme 2
(complete monitoring). Provides an EM algorithm for Weibull parallel
systems and Fisher information comparison across schemes. The k-out-of-n
framework unifies series (k=1) and parallel (k=m) systems as a censoring
problem on component lifetimes. Conforms to the 'likelihood.model'
generics and returns fitted objects compatible with 'algebraic.mle'. The
data-generating process and topology infrastructure (system survival,
density, signature, structure function, importance measures) are delegated
to the 'dist.structure' package; 'kofn' focuses exclusively on inference
for the k-out-of-n family.
