Data Science VC follow up: Intro to R and Statistics for the Rookie Part 1

20 Feb

I’ve decided to hold a five week introductory statistics and R course. Here, I am sharing the slide deck and the code. The video will go up on our YouTube Data Science Virtual Chapter channel, which is accessible from here.

In the first week, we talked about the relationship between statistics and data visualisation, and how it is extremely useful to have a good grounding in both topics. The slides are here, followed by the code:

The R code can be copied and pasted into your RStudio file:

# Loads sample datasets
data()

# Let’s look at the data
# This command tells you the metadata. What does R see, when it sees ‘iris’?
str(iris)

# What are the attributes?
# This gives us more information.
attributes(iris)

# Let’s see more of the data
iris

class(iris)
# A data frame has columns which can have different types.
# The column names and types constitute the schema.
# how do we know what is in our data frame?

# Column Names
colnames(iris)

# how can we see data in one of the columns?
iris$Petal.Length
# or we could also use iris[,3] to get the same column data.

iris[,3]
# of course, we want to visualise the data.
# Let’s do a simple scatter plot.

# How can we see the first five rows?
iris[1:5,]

# how can we see the Petal Length of the first 5 rows?
iris[1:5, “Petal.Length”]

# This shows us some of the descriptive statistics of each variable
summary(iris)

table(iris$Species)

# Let’s have some dataviz fun!
plot(iris$Petal.Length, iris$Petal.Width, main=”Anderson’s Iris Data”)
# You can now see the plot appear in the right hand side frame of RStudio.
# we can make it slightly more interesting
plot(iris$Petal.Length, iris$Petal.Width, pch=23, bg=c(“orange”, “blue”, “green”) [unclass(iris$Species)], main=”Anderson’s Iris Data”)

# we can make it even more interesting
pairs(iris[1:4], main = “Anderson’s Iris Data”, pch = 23, bg = c(“orange”, “green”, “blue”)[unclass(iris$Species)])
# pie charts!
pie(table(iris$Species))

# ooh, 3D!

library(scatterplot3d)
scatterplot3d(iris$Petal.Width, iris$Sepal.Length, iris$Sepal.Width)

# ooh, even more 3D!
library(rgl)
plot3d(iris$Petal.Width, iris$Sepal.Length, iris$Sepal.Width)

#Save your work!

PASS BA Speaker focus: What did Steve Jobs have to say about Daniel Fylstra?

17 Feb

PASS BA Conference is delighted to have Daniel Fylstra speaking at our conference. In fact, he was the first speaker we signed up.

Here’s what Steve Jobs had to say:

“There have been two real explosions that have propelled the industry forward. The first one really happened in 1977, and it was the spreadsheet. I remember when Dan Fylstra, who ran the company that marketed the first spreadsheet, walked into my office at Apple one day and pulled out this disk from his vest pocket and said “I have this incredible new program — I call it a Visual Calculator,” and it became VisiCalc. And that’s what really drove — propelled — the Apple II to the success it achieved.”

I think it’s great that we have such a visionary attending our PASS BA Conference. I’m looking forward to meeting Daniel, and picking up his insights from 30 plus years in the industry. Jobs mentions an event that took place when I was only six years old, and look at how the industry has grown since then. We have Excel’s 30th Birthday this year.

We can really say that the team of Dan Bricklin, Bob Frankston and Daniel Fylstra are great innovators who have really changed the industry fundamentally. Although they didn’t invent the spread sheet, it was Daniel Fylstra suggested it would be a viable product if it could run on an Apple II computer. VisiCalc was born.

Ever used the Microsoft Excel Solver? Well, here is Daniel Fylstra’s paper on the Microsoft Excel Solver, and its design and use. If you’ve ever used it, you should tip your hat to the great team who put it together. Daniel is one of those people. More recently, Fylstra has been working on Integrated simulation, data mining and optimization in Excel. Here’s a recent paper here, from the ACM.

From this insight, there are great innovators and thinkers that can we learn from them. They seek better ways of doing things, about bringing insights from other disciplines. We are inspired by people who see the bigger picture, and I’m personally looking forward to meeting Daniel and thanking him for all he has done for this industry.

Make sure you sign up for the Conference, and take the opportunity to meet a legend in the industry.

Jen Stirrup:

Here come the IBM experts! Here’s one our PASS BA Conference speakers, Richard Lee, sharing his expertise on the topic of data privacy. Richard is a well-respected influencer and strategist in data leadership, and we are delighted to have him join us at the event. Richard Lee is on of IBM’s Honours list as a Big Data and Analytics Hero, as well as on of their Champions.

Richard joins another IBM superstar, James Kobielus, who will be talking about Big Data. James G Kobielus is an industry veteran. He serves as IBM’s big data evangelist; as senior program director for product marketing in big data analytics, and as editor-in-chief of IBM Data Magazine. Kobielus spearheads IBM’s thought leadership activities in Big Data, Hadoop, cognitive computing, enterprise data warehousing, and advanced analytics. Basically, he is an expert in a variety of facets of big data.

Personally I cannot wait for their sessions. I’ve admired their work from afar and when we were selecting speakers, they went straight onto my wishlist. I have been lucky enough to meet Richard in person recently and we had a great conversation. I’m looking forward to meeting James as well; we’ve spoken on the phone. I learned things from conversing with both of them, and I’m sure that attendees will gain inspirational and practical advice from both of them.

Jen’ Diary: Board Meeting, BA Marathon, PASS BA features on TechNetRadio!

14 Feb

Here’s another diary entry for my time on the PASS board. I don’t represent PASS officially here. I know it has been quiet but I am busy on PASS, work, and other community things such as SQLSaturday Edinburgh and TechDays UK. So far this year, I have had one night off! It’s 2.30am here in the UK and I’m churning out a blog, so I can’t be accused of shirking!

If you are attending Pass BA Conference and looking for a discount, please email me at jen.stirrup@sqlpass.org and I have a discount code to give away.

I attended the PASS Board meeting in January, talking mainly about handing over the Virtual Chapters portfolio but the main focus of my time was the PASS BA Conference. We talked about our goals for the Portfolio, our progress so far, and our next steps. I also shared some marketing insights. I’m on the Program Committee, so I talked about our process for going out and getting the big names in the analytics industry – people who live and breathe analytics. It has been a lot of fun, but it has also been extremely hard work to get the right speakers. Our speaker list is here. We still have some names to release, so watch that space.

I’ve also been helping some of the sponsors with thoughts on their content and material. Hortonworks are going to put on a great session and you’ll get more details of that, in the future.

I also took part in the PASS BA Marathon. My session is here. Again, the PASS HA team did a great job of supporting this event and the sessions are extremely fresh. The speakers did an amazing job!

I was also part of the process in securing our amazing Day 2 keynote speaker, Mico Yuk. I have so many things to look forward to at PASS BA, and Mico’s session is a real highlight for me. Mico has many achievements, including one of the top 50 Analytic voices on Twitter. We are blessed to have her with us, and I can’t wait to hear her talk and to get to know her in person.

More good news! What did Microsoft’s Jen Moser, Jen Underwood and Miguel Martinez @sqljen @maikelson @idigdata say about the ‪#‎passbac‬ with TechNetRadio?

I’m so excited to be part of this opportunity to grow the business-focused data community, the data analyst, the business analyst, who works with data but doesn’t work in the IT department. It is a exciting growth in our approach and our fantastic speaker list reflects our vision about the emerging BA community and what they really want.

Miguel is correct; we worked hard to invite big name analytics speakers, and they are coming!
