Using regression with correlated data. Tutorial (including R code) for using Generalized Estimating Equations and Multilevel Models.
While regression models are easy to run given their short, simple syntax, this accessibility also makes it easy to use regression inappropriately. These models have several key assumptions that need to be met in order for their output to be valid, but your code will typically run whether or not these assumptions have been met.
For linear regression (used with a continuous outcome), these assumptions are as follows:
A data scientist/analyst in the making needs to format and clean data before being able to perform any kind of exploratory data analysis.
Learn the essential concepts in data science and understand the important packages in R for data science. You will look at some of the widely used data science algorithms such as Linear regression, logistic regression, decision trees, random forest, including time-series analysis. Finally, you will get an idea about the Salary structure, Skills, Jobs, and resume of a data scientist.
