WebbIn simple random sampling, the inclusion probabilities are equal for all population units. The advantage of this is simple and straightforward statistical inference. With equal inclusion probabilities the unweighted sample mean is an unbiased estimator of the spatial mean, i.e., the sampling design is self-weighting. Webb16 dec. 2024 · 3. I am self-studying some data clustering algorithms recently to solve a problem at work. Sometimes my data set is too big to perform k-means so I take a shortcut: (1) first randomly sample, without replacement, from the data set, then (2) perform k-means on the random sample, finally (3) assign the original data to the closest …
