Credit Card Customers Segmentation

Build an enriched customer profile using intelligent KPIs. Apply advanced algorithms like factor and cluster analysis for data reduction and customer segmentation based on the behavioral data.

Key Drivers for Customer Spending

The objective of this case study is to understand what's driving the total spend of credit card(Primary Card + Secondary card) and identify the key spend drivers . This will require candidates to apply OLS/ linear regression and follow end-to-end model building process

Proactive Attrition Management

Build a logistic regression based predictive model for a telecom service provider to identify churn indicators to predict and proactively manage the customer attrition.

Predicting Loan Default

Apply the logistic regression to identify the risky customers with high likelihood to default on loan repayment.

Time Series Forecasting

Use time series analysis to forecast the outbound passenger movement for next four quarters.

For how long are the recordings available to me?

One year post your course completion. Virtually the recordings are available to you for lifetime, but for judicious use of IT resources, the access to these recordings get deactivated post one year. However, this access can be extended upon request free of charge.

Can I download the recordings?

No. Our recordings can be accessed through your account on LMS or stream them live online at any point of time though.

Recordings are integral part of AnalytixLabs intellectual property by Suo Jure. The downloading/distribution of these recordings in anyway is strictly prohibited and illegal as they are protected under copyright act. Incase a student is found doing the same, it will lead to an immediate and permanent suspension in the services, access to all the learning resources will be blocked, course fee will be forfeited and the institute will have all the rights to take strict legal action against the individual.

What if I share my LMS login details with a friend?

The sharing of LMS login credentials is unauthorized, and as a security measure, if the LMS is accessed by multiple places, it will flag in the system and your access to LMS can be terminated.

Will I get a certificate in the end?

Yes. All our course are certified. As part of the course, students get weekly assignments and module-wise case studies. Once all you submissions are received and evaluated, the certificate shall be awarded.

Do you help in placements?

We follow a comprehensive and a self-sustaining system to help our students with placements. This is a win-win situation for our candidates and corporate clients. As a pre-requisite for learning validation, candidates are required to submit the case studies and project work provided as a part of the course (flexible deadline). Support from our side is continuous and encompasses help in profile building, CV referrals (as and when applicable) through our ex-students, HR consultants and companies directly reaching out to us.

We will provide guidance to you in terms of what are the right profiles for you based on your education and experience, interview preparation and conducting mock interviews, if required. The placement process for us doesn’t end at a definite time post your course completion, but is a long relationship that we will like to build.

Do you guarantee placements?

No institute can guarantee placements, unless they are doing so as a marketing gimmick! It is on a best effort basis.

In professional environment, it is not feasible for any institute to do so, except for a marketing gimmick. For us, it is on a best effort basis but not time – bound – in some cases students reach out to us even after 3 years for career support.

Do you have a classroom option?

No. For this course we don't provide a classroom option.

How can I reach out to someone if I have doubts post class?

Through the LMS, students can always connect with the trainer or even schedule one-to-one time over the phone or online. During the course we also schedule periodic doubts-clearing classes though students can also ask doubts of a class in the subsequent class.

LMS also has a discussion forum where a lot of your doubts might get easily answered.

Incase you are having a problem still, repeat the class and schedule one-to-one time with the trainer.

What is your refund policy?

  • Instructor Led Live online or Classroom - Within 7 days of registartion date and latest 3 days before batch start
  • Video-based - 2 days

What are the system requirements for the software?

There is no particular system requirement for this course since the tool required for this course (R) can easily be installed on almost every laptop with basic configuration available these days.

Can I pay in instalments?

No installment option is available for this course since it is a self-paced course.

AnalytixLabs is undoubtedly one of the best training institute for anyone aspiring to pursue career in field of Analytics. I was in my 3rd year B.tech(last year) when I joined this institute for training in Big Data Hadoop certification couse. I was new to this field and had no prior knowledge about it. But as the course proceeded and we got projects to work with(on weekly basis), and it really helped me a lot to constatanly evolve myself . After analytixlabs, I got the opportunity to work as intern in one of the big 4 audit firm during my college days only. I have personally interacted and worked with Chandra and Sumeet, and they are great persons to work with. Chandra has guided me even after the training was complete and even today I reach out to him for assistance in case of any problem. Feel free to reach out to teachers for any help beacause they are always there to help you, not only during tenure of the course but even after course is over.
