Welcome to the Data Science Specialization using R!

The Beginner’s Guide to the Data Science Specialization using R!

In my first video, I introduced the learners to the Data Science Specialization using R. I have covered topics such as data manipulation, data visualization, statistical inference, and machine learning. I have also talked about the importance of using R in data science and the benefits of the Data Science Specialization. You are now ready to dive deeper into the world of data science with R and learn from my expertise. If you haven't watched my first video please find it below:



Course Dependency Table:

To help my viewers better understand the structure and dependencies of the Data Science Specialization using R, I have provided a course dependency table. This table will show which courses build upon the knowledge learned in previous courses and which courses are prerequisites for others.

For the courses, we consider two forms of dependency:

  • Hard dependency: Students will be required to know material from the prerequisite course. Taking the dependent course simultaneously will be challenging and only possible for highly motivated students willing to work ahead of the course schedule for the prerequisite. Taking hard dependent courses out of order is not possible unless the student already knows the material covered in the prerequisite course.
  • Soft dependency: Knowledge of material from the prerequisite course is recommended and useful. Concurrently taking the prerequisite course and the dependent course is possible. It is not recommended to take them out of order, but would be possible for highly motivated students willing to self-teach components of the prerequisite course as needed.

What is Data? And What is Data Science Process?

The Beginner’s Guide to Data & Data Science Process About Data: In our First Video today we talked about Data and how the Cambridge English Dictionary and Wikipedia defines Data, then we looked on few forms of Data that are: Sequencing data   Population census data ( Here  is the US census website and  some tools to help you examine it , but if you aren’t from the US, I urge you to check out your home country’s census bureau (if available) and look at some of the data there!) Electronic medical records (EMR), other large databases Geographic information system (GIS) data (mapping) Image analysis and image extrapolation (A fun example you can play with is the  DeepDream software  that was originally designed to detect faces in an image, but has since moved on to more  artistic  pursuits.) Language and translations Website traffic Personal/Ad data (e.g.: Facebook, Netflix predictions, etc.) These data forms need a lot of preprocessin...

Efficient Data Manipulation with Loop Functions in R: A Deep Dive into apply and mapply

The Beginner’s Guide to Loop Functions in R: In addition to lapply and sapply , R also has apply and mapply , which are other loop functions that are commonly used for data manipulation and analysis. In this blog post, we'll explain what these functions are, how they work, and provide some practice material for beginners to intermediate level. apply:  Apply a Function to a Matrix or Array apply is a loop function in R that applies a function to either rows or columns of a matrix or array. Here's the basic syntax: apply(matrix/array, margin, function) The matrix/array argument is the matrix or array you want to apply the function to, and the margin argument specifies whether you want to apply the function to rows or columns. margin = 1 applies the function to rows, while margin = 2 applies the function to columns. The function argument is the function you want to apply. For example, let's say we have a matrix of numbers and we want to apply the sum function to each row:...

Optimization Example of Lexical Scoping in R: Exploring optim, optimize, and nlm Functions

The Beginner’s Guide to Optimization Example of Lexical Scoping in R: When it comes to optimization in R, lexical scoping can be a useful tool for optimizing complex functions that involve multiple variables. In this blog post, we will explore how lexical scoping can be used to optimize a function using the NLL (negative log-likelihood) function , and how the optim, optimize, and nlm functions can be used to perform optimization in R. Optimizing the NLL Function using Lexical Scoping The NLL function is a common function used in optimization problems. It is defined as the negative log of the likelihood function, which is used to estimate the parameters of a statistical model. In R, the NLL function can be defined using lexical scoping, which allows us to pass arguments to the function and access variables from within the function. Here is an example of how to define the NLL function using lexical scoping in R: nll <- function(data, parameters) {   # Define local variables ...
