Neutrosophic PPS Sampling: Lahiri Method with NHT and NGREG Estimators

Overview

neutroPPS implements a complete framework for Neutrosophic Probability Proportional to Size Without Replacement (PPSWOR) sampling and estimation using interval-valued (neutrosophic) data.

Main Function

neutro_pps()

Performs the full pipeline:

• Population summary
• Lahiri PPSWOR sampling (using Auxili_min as size measure)
• Neutrosophic first- and second-order inclusion probabilities
• Neutrosophic Horvitz-Thompson (NHT) and Neutrosophic Generalized Regression (NGREG) estimators
• Variance, CV, and relative efficiency measures

Installation

install.packages("neutroPPS")
library(neutroPPS)

Quick Example

data_neutro <- data.frame(
  Auxili_min = c(10, 15, 20, 25, 30),
  Auxili_max = c(12, 18, 25, 32, 40),
  Study_min  = c(50, 60, 75, 90, 110),
  Study_max  = c(55, 70, 85, 105, 130)
)

res <- neutro_pps(data_neutro, n = 2, seed = 12, verbose = TRUE)

res$ht      # View NHT results
res$greg    # View NGREG results
