The importance of data analytics lies at the neck of what type of analytics to be applied for which integral part of the data. Depending upon the nature and type of data, the utilization of the analytical types may also vary. The most important type of analytics which has been predominantly used up in health-care sector is survival analytics. The term survival analytics has originated from a medical domain of context which in turn determines and estimates the survival rate of patients. Among all the types of data analytics, survival analytics is the one which entirely depends upon the time and occurrence of the event. This chapter deals with the need for survival data analytics with an explanatory part concerning the tools and techniques that focus toward survival analytics. Also the impact of survival analytics with the real world problem has been depicted as a case study.
The result was the International Financial Reporting Standard 9 that became effective for all financial years beginning on or after 1 January . Previously impairment losses on financial assets were only recognised to the extent that there was an objective evidence of impairment, meaning a loss event needed to occur before an impairment loss could be booked . The new accounting rules for financial instruments require banks to build provisions for expected losses in their loan portfolio. The loss allowance has to be recognised before the actual credit loss is incurred. It is a more forward-looking approach than its predecessor with the aim to result in a more timely recognition of credit losses . A key credit risk parameter is the probability of default.
Health economic models rely on data from trials to project the risk of events e. Parametric survival analysis methods can be applied to identify an appropriate statistical model for the observed data, which can then be extrapolated to derive a complete time-to-event curve. This paper describes the properties of the most commonly used statistical distributions as a basis for these models and describes an objective process of identifying the most suitable parametric distribution in a given dataset. The approach can be applied with both individual-patient data as well as with survival probabilities derived from published Kaplan-Meier curves. Both are illustrated with analyses of overall survival from the Sorafenib Hepatocellular Carcinoma Assessment Randomised Protocol trial.

This special issue of the Review of Finance and Accounting presents six papers which use survival analysis as a research method to examine a wide range of research questions in accounting, economics, and finance. The papers assembled in this issue are written by authors who have previously demonstrated an interest in survival analysis. LeClere, M. Emerald Group Publishing Limited. Report bugs here.

Comparative study of different survival analysis models for bankruptcy prediction. Doctoral thesis, Nanyang Technological University, Singapore. However, to date, only few nonlinear techniques in survival analysis have been implemented in financial applications. A comprehensive comparison among the outputs from different models is conducted.
Parametric and semiparametric models are tools with a wide range of applications to reliability, survival analysis, and quality of life. This self-contained volume examines these tools in survey articles written by experts currently working on the development and evaluation of models and methods.
