Why do we need Analytics?

4. https://www.edureka.co/r-for-analyticsEDUREKA DATA ANALYTICS WITH R CERTIFICATION TRAINING
Why do we need Analytics?
➢ Below are some of the domains and the problems they face :
➢ Large amount of customer data
is generated everyday
➢ While dealing with millions of
customers on regular basis, it
becomes hard to track their
mortgages.
➢ Insurance domain extensively depends on
forecasting.
➢ By understanding the risk involved based
on credit report, it becomes easier to decide
which policy to accept or reject.
➢ Every year millions are admitted in
hospital.
➢ Billions are spent annually just in
the admission process.
Banking Insurance Healthcare

Why do we need Analytics?
➢ Below are the solution for the problems faced by different domains :
Banking Insurance Healthcare
➢ R builds a custom model that
maintains the loans provided to
every individual customer which
helps us to decide the amount to
be paid by the customer over time.
➢ By using the continuous credit report
as input, we can create a model in R
that will not only assess risk appetite
but also make a predictive forecast as
well.
➢ Given the patient history and
medical history, a predictive
model can be built to identify
who is at risk for hospitalization
and to what extent the medical
equipment be scaled

R is a Environment for Statistical Analysis
➢ Available in the R language are functions for
virtually every data manipulation, statistical
model, or chart that the data analyst could
ever need.

➢ Not only does this mean that you can
download and use R for free, but the
source code is also open for inspection
and modification to anyone who wants to
see how the methods and algorithms work
under the covers.
