NCCTG Lung Cancer Data

NCCTG Lung Cancer Data from survival in patients with advanced lung cancer is from the North Central Cancer Treatment Group. The data is a collection of few metadata, such as which institution collected it, age of the patient, sex, and so on. The performance scores in this dataset rates how well the patient can perform the daily activities. The most important variable in any survival analysis dataset is the knowledge about the time-to-event, for example, time until death.

Survival analysis is usually defined as a set of methods for examining data where the outcome variable is the time till the incidence of an event of interest.

Figure 4.21: Variables and its descriptions of North Central Cancer Treatment Group

In the next exercise, we will learn how to create the survival object using the method Surv from the survival package. Note that in the summary of the dataset after adding the survival object, two additional variables SurvObject.time and SurvObject.status are created...

Jojo Moolayil

Jojo Moolayil is a data scientist, living in Bengaluru—the silicon valley of India. With over 4 years of industrial experience in Decision Science and IoT, he has worked with industry leaders on high impact and critical projects across multiple verticals. He is currently associated with GE, the pioneer and leader in data science for Industrial IoT. Jojo was born and raised in Pune, India and graduated from University of Pune with a major in information technology engineering. With a vision to solve problems at scale, Jojo found solace in decision science and learnt to solve a variety of problems across multiple industry verticals early in his career. He started his career with Mu Sigma Inc., the world's largest pure play analytics provider where he worked with the leaders of many fortune 50 clients. With the passion to solve increasingly complex problems, Jojo touch based with Internet of Things and found deep interest in the very promising area of consumer and industrial IoT. One of the early enthusiasts to venture into IoT analytics, Jojo converged his learnings from decision science to bring the problem solving frameworks and his learnings from data and decision science to IoT. To cement his foundations in industrial IoT and scale the impact of the problem solving experiments, he joined a fast growing IoT Analytics startup called Flutura based in Bangalore and headquartered in the valley. Flutura focuses exclusively on Industrial IoT and specializes in analytics for M2M data. It is with Flutura, where Jojo reinforced his problem solving skills for M2M and Industrial IoT while working for the world's leading manufacturing giant and lighting solutions providers. His quest for solving problems at scale brought the 'product' dimension in him naturally and soon he also ventured into developing data science products and platforms. After a short stint with Flutura, Jojo moved on to work with the leaders of Industrial IoT, that is, G.E. in Bangalore, where he focused on solving decision science problems for Industrial IoT use cases. As a part of his role in GE, Jojo also focuses on developing data science and decision science products and platforms for Industrial IoT.
