Projects Which Students Will Develop

For this project, you should perform exploratory data analysis on different file types like XML, JSON, TEXT, .DAT (data will be provided by ACADGILD)

This project aims at creating a Multiple Linear Regression Model for General motors (GM) data set. The data set contains data based on several hundred used General Motors (GM) cars. The data allows us to develop a multivariate regression model to determine car values based on a variety of characteristics such as mileage, make, model, cruise control, etc.

Aim of this project is to build a stock trading system based on prediction models obtained with daily stock quotes data. Several models will be tried with the goal of predicting the future returns of the S&P 500 market index.

This project aims at creating a Linear Regression Model for DVD sales data set which contains the following details - “ Advertising, Sales, Plays and Attractiveness.

This project aims at:

a) Writing R code to calculate the amount of money owed after n years inn a problem state

a) Writing R code to calculate the amount of money owed after n years inn a problem state

Customers Feedback

The training provided is very good, especially on AngularJS. It would have been good if we have involved in the final project on AngularJs development. Overall the training met the expectation.

The way of ACADGILD Mentor , Krish Ram teach is easily understand and easy learning with good clarity about the subject knowledge along with practical examples.He always makes us to understand by giving real time and interesting examples.The support and co-operation from the team is great and i am feeling happy to doing course here.

I joined AcadGild's Front End Development course about a month back. So far my experience has been great. And now I am really glad I took this course. The focus on coding while learning sessions and the bunch of tips after session to solve assignments gave the load hands on experience.

I am Jayanth Kumar T, a Senior Research Engineer. I took up the Front End course at AcadGild. The course definitely helped me add skills to my resume.The mentors were disciplined, knowledgeable and provided a good support. Thank you all for the support during the course.

My name is Vyshali Bhat. My mentor, Mr. Jayant has been very supportive and it was a very good learning experience for me. I wish to thank the Acadgild team for all the support and guidance.

FAQ's

R is a programming language and software environment for statistical computing and graphics. R allows you to visualize data, run statistical tests, and apply Machine Learning algorithms. In this course, you will learn about the most effective data analytic techniques and gain practice by implementing them and getting them to work for you. More importantly, you'll learn about not only the theoretical underpinnings of learning but also gain the practical know-how needed to quickly and powerfully apply these techniques to new problems.

Graduate students, post graduate, and Ph.D scholars (from statistical background), entry-level software professionals, and anyone who is interested in a data analytics career

After completion of this course, one can have a solid understand of practical issues in statistical computing which includes programming in R, reading data into R, accessing R packages, writing R functions, debugging, profiling R code, and organizing and commenting R code.
