2. Oversampling and undersampling in data analysis - Wikipedia

   en.wikipedia.org/wiki/Oversampling_and_under...

   Within statistics, oversampling and undersampling in data analysis are techniques used to adjust the class distribution of a data set (i.e. the ratio between the different classes/categories represented). These terms are used both in statistical sampling, survey design methodology and in machine learning.

3. Inverse transform sampling - Wikipedia

   en.wikipedia.org/wiki/Inverse_transform_sampling

   Inverse transform sampling (also known as inversion sampling, the inverse probability integral transform, the inverse transformation method, or the Smirnov transform) is a basic method for pseudo-random number sampling, i.e., for generating sample numbers at random from any probability distribution given its cumulative distribution function.

4. Simple random sample - Wikipedia

   en.wikipedia.org/wiki/Simple_random_sample

   If a systematic pattern is introduced into random sampling, it is referred to as "systematic (random) sampling". An example would be if the students in the school had numbers attached to their names ranging from 0001 to 1000, and we chose a random starting point, e.g. 0533, and then picked every 10th name thereafter to give us our sample of 100 ...

5. Sampling (statistics) - Wikipedia

   en.wikipedia.org/wiki/Sampling_(statistics)

   A visual representation of the sampling process. In statistics, quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within a statistical population to estimate characteristics of the whole population.

6. Stratified randomization - Wikipedia

   en.wikipedia.org/wiki/Stratified_randomization

   Graphic breakdown of stratified random sampling. In statistics, stratified randomization is a method of sampling which first stratifies the whole study population into subgroups with same attributes or characteristics, known as strata, then followed by simple random sampling from the stratified groups, where each element within the same subgroup are selected unbiasedly during any stage of the ...

   en.wikipedia.org/wiki/123Movies

   123Movies, GoMovies, GoStream, MeMovies or 123movieshub was a network of file streaming websites operating from Vietnam which allowed users to watch films for free. It was called the world's "most popular illegal site" by the Motion Picture Association of America (MPAA) in March 2018, [3] [6] before being shut down a few weeks later on foot of a criminal investigation by the Vietnamese ...

8. Probability-proportional-to-size sampling - Wikipedia

   en.wikipedia.org/wiki/Probability-proportional...

   The pps sampling results in a fixed sample size n (as opposed to Poisson sampling which is similar but results in a random sample size with expectancy of n). When selecting items with replacement the selection procedure is to just draw one item at a time (like getting n draws from a multinomial distribution with N elements, each with their own ...
