Pick any 2 things that you use in your daily life and that are related.

Like, I have data of my monthly spending, monthly income and the number of trips per month for the last 3 years.

Examples of Statistical Learning problems include: In my last semester in college, I did an Independent Study on Data Mining.

The class covers expansive materials coming from 3 books: Intro to Statistical Learning (Hastie, Tibshirani, Witten, James), Doing Bayesian Data Analysis (Kruschke), and Time Series Analysis and Applications (Shumway, Stoffer).

While having a strong coding ability is important, data science isn’t all about software engineering (in fact, have a good familiarity with Python and you’re good to go).

Data scientists live at the intersection of coding, statistics, and critical thinking.

This approach identifies a subset of the has the effect of reducing variance.

Depending on what type of shrinkage is performed, some of the coefficients may be estimated to be exactly zero. The two best-known techniques for shrinking the coefficient estimates towards zero are the In statistics, nonlinear regression is a form of regression analysis in which observational data are modeled by a function which is a nonlinear combination of the model parameters and depends on one or more independent variables.

As Josh Wills put it, I personally know too many software engineers looking to transition into data scientist and blindly utilizing machine learning frameworks such as Tensor Flow or Apache Spark to their data without a thorough understanding of statistical theories behind them.

So comes the study of statistical learning, a theoretical framework for machine learning drawing from the fields of statistics and functional analysis. It is important to understand the ideas behind the various techniques, in order to know how and when to use them.
