What Is the Purpose of Sampling in Research?

Importance sampling is a variance reduction technique that can be used in the Monte Carlo method. The idea behind importance sampling is that certain values of the input random variables in a simulation have more impact on the parameter being estimated than others. If these "important" values are … Zobacz więcej Importance sampling is a Monte Carlo method for evaluating properties of a particular distribution, while only having samples generated from a different distribution than the distribution of interest. Its introduction … Zobacz więcej Such methods are frequently used to estimate posterior densities or expectations in state and/or parameter estimation problems in probabilistic models that are too hard to treat analytically, for example in Bayesian networks Zobacz więcej • Sequential Monte Carlo Methods (Particle Filtering) homepage on University of Cambridge • Introduction to importance sampling in rare-event simulations Zobacz więcej Let $${\displaystyle X\colon \Omega \to \mathbb {R} }$$ be a random variable in some probability space $${\displaystyle (\Omega ,{\mathcal {F}},P)}$$. We wish to estimate the expected value of X under P, denoted E[X;P].
