Bayesian inference is a statistical method used to update the probability of a hypothesis or parameter based on new evidence or data. It involves incorporating a prior probability distribution and likelihood function into a formula, which yields a posterior probability distribution. This approach allows for uncertainty to be quantified and updated as more data is collected, making it a powerful tool for decision-making and prediction in a wide range of fields, including finance, healthcare, and science. However, Bayesian inference requires specialized expertise in probability theory, statistical modelling, and computational methods.

Bayesian Statistics refers to a statistical paradigm that incorporates prior knowledge or beliefs, along with new evidence, to update the probability of a hypothesis. This skill involves the application of Bayes' theorem to model uncertainty and make inferences based on data. Bayesian Statistics is used in various fields, including medicine, finance, and machine learning, to improve decision-making processes by quantifying uncertainty and refining predictions as more information becomes available.

Dplyr is a package in the R programming language that provides an efficient and intuitive way to manipulate and filter data sets. It offers a set of functions that operate on data frames, including selecting columns, filtering rows, summarising data, and more. Dplyr is a powerful tool for data wrangling and is commonly used in data science and analysis projects.

Hierarchical Clustering refers to a method of cluster analysis that seeks to build a hierarchy of clusters. This skill involves creating a tree-like structure, known as a dendrogram, which visually represents the arrangement of data points based on their similarity. Hierarchical Clustering is used in various fields, including biology for classifying species, marketing for segmenting customers, and data analysis for organizing large datasets, enabling users to identify patterns and relationships within the data.

Machine Learning Methods refer to a set of algorithms and statistical techniques that enable systems to learn from data and improve their performance over time without explicit programming. This skill encompasses various approaches, including supervised, unsupervised, and reinforcement learning, which are utilized to analyze patterns, make predictions, and inform decision-making processes. Knowledge of Machine Learning Methods is applied in diverse fields such as finance, healthcare, and marketing to enhance data-driven insights and automate complex tasks.
