Clinical trials can be defined as an experiment which is conducted in a controlled environment to test the efficacy of drugs, procedures, methodology before bringing into the public domain. The clinical trials started in 2nd century BC by Daniel & King Nebuchadnezzar. Formal recorded therapeutic clinical trial was started way back in 1537 AD by a Surgeon. Current clinical trials include clear guidelines, adhering to regulatory requirements, getting consent from the patients, ensuring safety of the patients, adopting ethical practices, close monitoring of the trials and using advanced statistical tools to analyze and report the findings. Advancement in technology such as cloud computing, big data analytics, machine learning algorithms, data base management and advanced statistical software helped to transform the different stages of clinical trials - the data collection, data storage, data monitoring, data management and data analysis. This book provides an overview of clinical trials, different phases & types of clinical trial, randomization, blinding, allocation, ethical issues, protocol, data collection forms, data management, data analysis and reporting of the clinical trial. It is recommended to refer author's book on Application of Statistical Tools in Biomedical Domain: An Overview with Help of Software (https: //www.amazon.com/dp/1986988554) and Essentials of Bio-Statistics: An overview with the help of Software https: //www.amazon.com/dp/B07GRBXX7D if you need to familiarize yourself with the basic statistical knowledge.

This book is an edited book from the papers of International Journal of Statistics and Medical Informatics authored by Editor, International of Statistics and Medical Informatics. It covers topics such as systematic review and meta-analysis, factor analysis, structural equation modelling and quantile regression in the field of biomedical domain. It also provides insight into the post hoc comparison, clinical trail data management and natural language processing

R programming has gained importance in different fields due its flexibility, rich packages, platform independent characteristics, data analysis & data visualization capabilities and building various models like machine learning models. It facilitates the incorporation of codes of other languages such as C, C++ and Java in its programming environment. R programming is an open source platform which is developed by Ross Ihaka and Robert Gentleman from University of Auckland during the year 1991. It is a modified version of S language developed during 1976 by Bell Laboratories in USA. Currently the development process is being handled by the R core development team. The book starts with the basic concepts such as vectors, objects, factors, data frames, lists, reading data and writing data files, conditions, controls, functions and handling database connections. Book covers the R Programming rich graphical and data visualization tools, and web applications. Statistical concepts such as Descriptive, Inferential, and regression models are also covered. It also includes Machine Learning models such as classification and clustering models. All the data files used in book can be downloaded from author's book website.

Statistical Methods are widely used in Medical, Biological, Clinical, Business and Engineering field. The data which form the basis for the statistical methods helps us to take scientific and informed decisions. Statistical methods deal with the collection, compilation, analysis and making inference from the data. The book mainly focuses on non-parametric aspects of Statistical methods. Non parametric methods or tests are used when the assumption about the distribution of the variables in the data set is not known or does not follow normal distribution assumption. Non parametric methods are useful to deal with ordered categorical data. When the sample size is large, statistical tests are robust due to the central limit theorem property. When sample size is small one need to use non-parametric tests. Compared to parametric tests, non-parametric tests are less powerful i.e. if we fail to reject the null hypothesis even if it is false. When the data set involves ranks or measured in ordinal scale then non-parametric tests are useful and easy to construct than parametric testsThe book uses open source R statistical software to carry out different non-parametric statistical methods with sample datasets.

Statistical methods are now widely used in different fields such as Business and Management, Economics, Biological, Physical sciences and including the new fields such as Data Science and Machine Learning. The data which form the basis for the statistical methods helps us to take scientific and informed decisions. Statistical methods deal with the collection, compilation, analysis and making inference from the data.This book deals with the statistical methods which are useful in Business and Management decision making. The methods include Probability, Sampling, Correlation, Regression and Hypothesis Testing, Time Series, Forecasting and Non-Parametric tests and advanced statistical models. The book uses open source R statistical software to carry out different statistical analysis with sample datasets. This book is third in series of Statistics books by the Author. Some of the contents are adopted from the author's previous statistical book introduction to statistical methods and non-parametric methods.
