Hi, I'm Daniela. I'm actually an Economist 😁, but am trying to learn more about machine learning, data-science etc., so thought I'd join the community!


Thank you so much Erin - this is so helpful!

How to solve this Bayes' theorem problem?


I'm stuck trying to solve the problem below...

A test for Hepatitis C is given to a population of possible carriers. It is believed that only $10\%$ are positive. The test itself is only $95\%$ accurate for people who have Hepatitis C, and $80\%$ accurate for those who do not have the disease. What is the probability that a person has Hepatitis C given a positive result?

I know that I'm going to have to use Baye's theorem to solve it, but don't really know how?

If anybody could give me a hint, I'd be very grateful!

I recently read "If you sit for more than three hours every day you're cutting nearly two years off of your life expectancy" which I found pretty shocking. Unfortunately I have no idea of the validity of the research.

What's the Best Way to Learn Machine Learning 🤖?


I was wondering whether people could recommend materials to help me learn machine learning? My goal is to gain an intuitive understanding of each of the algorithms, and to be able to work with them in Python/ R.

Hi I'm Daniela.

I'm doing an Economics and Management degree at St Andrews, and thought I could use this site for a little extra help with statistics. I'm also very keen to meet other statisticians/ economists.

For most of the summer I've been working at a children's summer camp, but when I'm not doing that, I'm usually dancing or swimming.

Hi Jordan! Welcome to Black Swans. Make sure to keep us posted on your chess machine. It sounds amazing !

I think Black Swans meetups would be a great idea! I would love to meet other stats students! Maybe we could try and get well-known statisticians, or CEOs of data-science companies to come in and give presentations as well as students?
