00:00:04,500 --> 00:00:08,580
Welcome to 15.071x,
the Analytics Edge.

2
00:00:08,580 --> 00:00:12,430
I'm Allison O'Hair, and together
with Dimitris Bertsimas,

3
00:00:12,430 --> 00:00:15,260
we'll be the instructors
for this course.

4
00:00:15,260 --> 00:00:17,720
During this week, we'll
start with an introduction

5
00:00:17,720 --> 00:00:20,070
to analytics and
to the topics we'll

6
00:00:20,070 --> 00:00:22,110
cover throughout the course.

7
00:00:22,110 --> 00:00:23,820
Then in the second
lecture, we'll

8
00:00:23,820 --> 00:00:27,060
introduce R, a statistical
modeling language that we'll

9
00:00:27,060 --> 00:00:29,320
use throughout
most of the course.

10
00:00:29,320 --> 00:00:32,100
The recitation and homework
assignment this week

11
00:00:32,100 --> 00:00:35,410
were designed to give you
more practice working in R.

12
00:00:35,410 --> 00:00:38,470
And by the end of the week,
we hope that you'll already

13
00:00:38,470 --> 00:00:41,190
be convinced about
the power of data.

14
00:00:41,190 --> 00:00:43,150
Let's get started.
