A BASIC program to produce random samples without replacement

Accelerating weighted random sampling without replacement

Random sampling from discrete populations is one of the basic primitives in statistical computing. This article briefly introduces weighted and unweighted sampling with and without replacement. The case of weighted sampling without replacement appears to be most difficult to implement efficiently, which might be one reason why the R implementation performs slowly for large problem sizes. This p...

A Computer Program for Solving LP Problems by 2-Basic Variables Replacement at Each Simplex Iteration

In this paper, we develop a computer technique to implement the existing 2-basic variable replacement method of Paranjape for solving linear programming (LP) problems. To our knowledge there is no such computer oriented program which implemented Paranjape’s method. Our computer oriented program is a faster method for solving linear programs. A number of numerical examples are illustrated to dem...

Generating Antithetic Random Variates in Simulation of a Replacement Process by Rejection Method

When the times between renewals in a renewal process are not exponentially distributed, simulation can become a viable method of analysis. The renewal function is estimated through simulation for a renewal process simulation for a renewal process with gamma distributed renewal times and the shape parameter a > 1. Gamma random deviates will be generated by means of the so called Acceptance Rejec...

Random deposition model with friction: Equivalent to ballistic deposition without lateral growth

The Random Deposition model is the simplest model for surface growth, where there is no correlation between the neighbor sites of the lattice. In the Ballistic deposition model, the particles stick to the first neighbor particle; thus it is used to describe the deposition of the sticky particles. However, in many true-life phenomena involving surface growth, there is no adhesion. Instead, the f...
