Numerical efficiency is obtained by utilizing the band matrix structure of the posterior precision matrices P j of the regression parameters β j. WebSampling strategies vary widely across different disciplines and research areas, and from study to study. There are two major types of sampling – probability and non-probability sampling. Probability sampling, also known as random sampling, is a kind of sample selection where randomisation is used instead of deliberate choice.
WebSampling is a method used in statistical analysis of a data where a specific number of samples are taken from a population for a study.
