Last week I ended the blogpost saying I would share results from the Kaggle survey this week, but actually there’s something else I want to talk about first Sample size In social science research we are mostly working with data collected by someone else. That’s because the scale of the survey data we need to be representative of a country or multiple countries is too big and too expensive for one person to collect by themselves.
This week I am trying to embed a shiny app on a static website using blogdown. In a couple of weeks I get to present a short introduction of blogdown at the first ever R-ladies meetup in the Netherlands following a presentation on Rmarkdown and Shiny1. It will be a nice bonus if I can show how to embed shiny apps in blogdown! Kaggle tech survey For this demonstration I’m going to use data from the freely available Kaggle survey on data science and machine learning.
Just as the original Titanic VHS was published in two video cassettes, this Titanic analysis is also being published in two posts. In this post–part 2–I’m going to be exploring random forests for the first time, and I will compare it to the outcome of the logistic regression I did last time. Random forest vs. Logistic regression Last time I explained how logistic regression uses a link function transforms non-linear relationships into linear ones.
Yes, this is yet another post about using the open source Titanic dataset to predict whether someone would live or die. At this point, there’s not much new I (or anyone) can add to accuracy in predicting survival on the Titanic, so I’m going to focus on using this as an opportunity to explore a couple of R packages and teach myself some new machine learning techniques. I will be doing this over two blog posts.
It’s the second day of 2018, which means time to start acting on my new year’s resolution to start a data blog. In the coming year I aim to post old and new data analysis projects, and in doing so learn more about markdown, R, A/B testing, data analysis, web design, and more. In pursuit of improving my blogging skills, I will also be following more blogs, so feel free to send me your blogs!
