bivgeom

cran
99.99th

Percentile

Implements Roy's bivariate geometric model (Roy (1993) <doi:10.1006/jmva.1993.1065>): joint probability mass function, distribution function, survival function, random generation, parameter estimation, and more.

99.99th

Percentile

Probability mass function, distribution function, quantile function, random generation and parameter estimation for the discrete inverse Weibull distribution.

99.99th

Percentile

Probability mass function, distribution function, quantile function, random generation and estimation for the skew discrete Laplace distributions.

99.99th

Percentile

Probability mass function, distribution function, quantile function, random generation and parameter estimation for the type I and III discrete Weibull distributions.

ForImp

Percentile

Imputation of missing values in datasets of ordinal variables through a forward imputation algorithm

GenForImp

cran
99.99th

Percentile

Two methods based on the Forward Imputation approach are implemented for the imputation of quantitative missing data. One method alternates Nearest Neighbour Imputation and Principal Component Analysis (function 'ForImp.PCA'), the other uses Nearest Neighbour Imputation with the Mahalanobis distance (function 'ForImp.Mahala').

GenOrd

cran
99.99th

Percentile

A gaussian copula based procedure for generating samples from discrete random variables with prescribed correlation matrix and marginal distributions.

99.99th

Percentile

Reliability of (normal) stress-strength models and for building two-sided or one-sided confidence intervals according to different approximate procedures.

99.99th

Percentile

Functions for drawing samples according to Sunter's sampling design, and for computing first and second order inclusion probabilities
