Keywords: SURVEY SAMPLING; A/B TEST; QUEUE MODELS; MACHINE LEARNING; OPTIMAL IMPLANTS; DISTRIBUTION FAMILIES. Objectives: further development of probabilistic and statistical methods and their application in different fields. Methodology description: The research was partly theoretical and partly practical in nature. Probabilistic methods, statistical data analysis procedures and machine learning algorithms were used, also statistical simulations were conducted. Software: R and Python programming environments. Results: A parameter estimating method for the difference in conversion rates is proposed, which allows to reduce variances and make quick business decisions during sequential A/B testing. A method for statistical analysis of the household data of a hypothetical town StatVillage has been developed, which provides a number of advantages for studying a course on survey sampling. An algorithm has been constructed that allows calculating the probabilities of states of an M/M/n queue with a predetermined accuracy over a given period of time, taking into account the economic effect of servicing. Distributions of femoral canal anthropometric characteristics have been obtained and a regression relationship between certain anthropometric characteristics has been established, which can be the basis for choosing the optimal shape of the implant. Several families of distributions have been constructed for the purpose of modeling financial data.  Product Description popup.authors Bondarenko Yana S. Karnaukh Yevhen V.
