Faster Versions of R

As you know, R software is widely used among statisticians and data scientists for statistical computing, data analysis and graphing. One of the major reasons for its popularity is that it is free and open-source, and another one is because of its huge external package support, that lets you solve any statistical problem. In spite of its popularity and numerous advantages however, R software users often complain about the vexing issue of memory. For anyone who works with large datasets, often with just a laptop setup, with 64-bit processor and 4 GB of RAM, they face issues with high computation times and additional memory (e.g., 18GB of RAM) for smooth processing.

Intuition of Naïve Bayes

Naïve Bayes is one of the most basic machine learning technique used for Classification.

Let’s look at how this algorithm works with an example. In the credit card industry, clients are always looking for methods to help classify customers as good or bad. A good customer is one who does not default on his payments as opposed to a bad customer. Let’s consider two such features (say maybe Income and credit limit of the person) that helps us distinguish between good and bad customers. Let’s plot a scatter plot between them that help us classify the customers.

In the following graph, the red data points represent bad customers and the blue point represents good customers. This you can consider as the training data.

Proc Univariate and Outlier Cutting

When we build statistical models, it is important to cross check the sanity of the data as there is always a risk involved that the data may not be as per expectations. This may lead to biased results and it is best to detect such issues early on in the study. One such anomaly is that of an outlier. Outlier is by definition an improbable value or a value that maybe a slightly far off from the general trend of the existing data. When outliers become extreme observations at either the left or the right it could alter the assumptions made by the statistician about the behaviour of the given population. Note that not all extreme observations are outliers and not all outliers are always extreme observations. Data quality is essential for the trustworthiness of the final analysis.
