 So we've done all the hard work. We're going to bring in our data set in a comma separated values format into Julia Yeah, I am in Julia box where we are going to continue doing our work and I've logged in using my Google account at the top Remember you'll see these tabs and when you're going to files You can simply navigate to the folder that you are going to work in that you are going to get your Julia file in and you can simply from your computer drag on to this area on the right your comma Separated values file it will then upload Into the Amazon web services and you can use it right there. So let's go back to our I Julia And this is where it is CCS dot CSV You can see it there That is the comma separated values and case controls series is the file the Julia file that I am going to work with Now I've already created it here. I've done all the hard work I've done all the typing so that we don't waste time in that you can either get the file yourself or you can Do all your own typing you see it's Julia 0.3.11 the file is opened up Remember Julia the Jupiter notebook here if I double click on a cell You see it is a markdown cell and I can use either html tags or markdown shortcuts like this The pound sign hashtag sign means h1 Equivalent to h1 and html so that will be the largest text a heading type one text if I Execute that cell beautiful nice text there for us As always I'm going to start my Julia coding Just to see if things are working properly I'm going to call the addition function they pass a two arguments So we know that's the same as writing 2 plus 2 and if I execute that line of code learn behold 4 I kind of know that everything is working now. So what are we going to get up to just using Julia here? I'm going to show you how to import the packages and the packages that we are going to use to do the statistical analysis on the data that we've worked so hard on to get we Going to show you how to import that data using the data frames package that is We're going to change the coded values remember we wanted to protect the identity of the patients We've changed some of the values we've used code words and I'm just going to show you how to revert that back to something that we can understand while we do the analysis Although you can leave it as such except for the actual values that you changed words not so much But the values we've got to bring back Remember we changed the for instance the ages of all the patients We can't analyze that because that won't be a true reflection of our sample We're also going to have a look around at the imported data set I'll show you how to get to certain cells how to get to certain columns only display them We're going to do some descriptive statistics that Including some simple plotting using the get fly package now We're not going to get into any depth in the get fly package, but it's so beautiful just to to Plot some of your data It's a nice way for human being to get start getting a feeling for where the data is going to go Together with that just some easy descriptive statistics and then we're going to make groups and we're going to compare them We're going to do some inferential statistics using the hypothesis tests package Including showing you how to do a test to decide for continuous numerical data to decide between a parametric and a non-parametric test So a lot of exciting stuff in this part of this lesson
