lsei - Solving Least Squares or Quadratic Programming Problems under Equality/Inequality Constraints

It contains functions that solve least squares linear regression problems under linear equality/inequality constraints. Functions for solving quadratic programming problems are also available, which transform such problems into least squares ones first. It is developed based on the 'Fortran' program of Lawson and Hanson (1974, 1995), which is public domain and available at <http://www.netlib.org/lawson-hanson/>.

npsurv - Nonparametric Survival Analysis

Non-parametric survival analysis of exact and interval-censored observations. The methods implemented are developed by Wang (2007) <doi:10.1111/j.1467-9868.2007.00583.x>, Wang (2008) <doi:10.1016/j.csda.2007.10.018>, Wang and Taylor (2013) <doi:10.1007/s11222-012-9341-9> and Wang and Fani (2018) <doi:10.1007/s11222-017-9724-z>.

nspmix - Nonparametric and Semiparametric Mixture Estimation

Mainly for maximum likelihood estimation of nonparametric and semiparametric mixture models, but can also be used for fitting finite mixtures. The algorithms are developed in Wang (2007) <doi:10.1111/j.1467-9868.2007.00583.x> and Wang (2010) <doi:10.1007/s11222-009-9117-z>.

cplots - Plots for Circular Data

Provides functions to produce some circular plots for circular data, in a height- or area-proportional manner. They include bar plots, smooth density plots, stacked dot plots, histograms, multi-class stacked smooth density plots, and multi-class stacked histograms.
