Comparision of Snowball Sampling and Sequential Sampling Technique
Representing against population with a subset of it is termed as sampling. Sampling can either be statistical or non-statistical. In statistical sampling (probability sampling technique) calculating the probability of getting any particular sample is possible. It is scientific and every element stands an equal chance of being selected. In statistical sampling, workforce, time and money highly l...

متن کاملComposite Estimators for Complex Sampling
Interest in on-line surveys aroused in the middle of the nineties, that is since questionnaires in HTML were first drawn up. The main questions that statisticians should always formulate when they plan an on-line survey are the following: which are the kinds of investigations we can carry out; which are the target finite population and the sample space, the inclusion probabilities and the pecul...
متن کاملEmpirical Analysis of Sampling Based Estimators for Evaluating RBMs
The Restricted Boltzmann Machines (RBM) can be used either as classifiers or as generative models. The quality of the generative RBM is measured through the average log-likelihood on test data. Due to the high computational complexity of evaluating the partition function, exact calculation of test log-likelihood is very difficult. In recent years some estimation methods are suggested for approx...
متن کاملA Snowball Sampling Approach for Studying Digital Minority Languages
This thesis discusses the methods used to assess the linguistic diversity of the internet. I critique the current literature on internet language diversity, arguing that existing methods-which aggregate textual data from many languages, to the exclusion of video and audio data-are unsuited to the study of minority languages. To address these shortcomings, I propose a snowball sampling approach ...
