Total Time on Test plot and routines for parameter estimation of
any lifetime distribution implemented in R via maximum likelihood (ML) given
a data set. It is implemented thinking on parametric survival analysis, but
it feasible to use in parameter estimation of probability density or mass
functions in any field. The main routines 'maxlogL' and 'maxlogLreg' are
wrapper functions specifically developed for ML estimation. There are
included optimization procedures such as 'nlminb' and 'optim' from base
package, and 'DEoptim' Mullen (2011) <doi:10.18637/jss.v040.i06>. Standard
errors are estimated with 'numDeriv' Gilbert (2011)
<https://CRAN.R-project.org/package=numDeriv> or the option 'Hessian = TRUE'
of 'optim' function.
