I recently used a R script from Keith McNulty to analyse my Facebook data. I was curious to know how much I had been posting for the past 10 years, but I also wanted to know much information Facebook had about me.
I was able to download over 4,000 days of data and more than 30,000 posts. These posts were mine, but also from friends that were posting on my timeline.
In the process, I learned these three points:
1. I have 1000’s of posts per year
I remember when I initially joined Facebook, my friends I would basically communicate and organise everything by posting publicly on our walls (no sense of privacy!).
The MSc in Business analytics is an intense year of rigorous technical and quantitative training. It prepares students to solve business problems using a variety of statistical, operations research and machine learning techniques.
What you learn in class is usually just a small part of what you end up doing in group projects and homework. There is a huge amount of good resources you can use to learn new material or enhance your knowledge in a topic.
In this blog, I wanted to share the most useful sources I found in case you’re planning to pursue this program at Imperial.
Before you start the program: the basics
Statistics and probability
Start by revising your math skills in statistics and probability.
A day at Imperial can involve lectures, homework, trainings and much more.
On a recent “normal Tuesday” at Imperial, I realised the interesting activities I was doing, which I’ll be sharing in this post:
Morning: Data Visualisation for Network Analytics
For our first homework in Network Analytics, we were asked to visualise correlations between stocks. As an investor, you’re interested in diversifying risk by selecting different types of them. You therefore want visualise which stocks behave similarly (positive correlations) or very differently (negative correlations).
Learning a new library is always demanding, but at least the results looked fascinating (spoiler alert: I’m a data visualisation fan).
Yesterday I attended my first ever hackathon, held at the Natural History Museum in London.
A perk of having a NERC funded studentship is priority attendance on the NERC Advanced training courses, and I was fortunate to gain a place on the Systematic review and meta-analysis for environmental sciences held at Royal Holloway University. Meta-analysis is a statistical technique used to combine results from different studies to identify patterns among studies, the strength of this is a higher statistical power is achieved than that of a single study. It was originally developed in medicine to gauge the effectiveness of treatments but is increasingly being applied to ecology.
We started off with lectures on the different types of reviews and an introduction to meta-analysis.
