10 lines of R code to fit a regression model to each country of the world to estimate yearly population growth rate for each country.

We fit a Logistic Regression model with repeated CV and achieve 95% accuracy in predicting the gender of the penguins ! Also tune the model further for more accuracy and precision !

In this example, we take sample from a binomial distribution with P = 0.50. We take 100 samples continuously, and at each sample we estimate P from the sample using sample observations. We see as the sample size reaches 100, the estimate converges very close to 0.50.

Multicollinearity occurs when there is significant correlation in predictor (x variable) variable in regression model. This causes serious problems, such as high variance and non-significance in coefficients (beta). We can visualize this using a simple 3d chart as given below.

This is a Team Performance Tracking Dashboard.This is a big team. The team is called Engineering and Analytics team at a company. Engineering team has two subteams > IT and Infrastructure. Analytics Team has three subteams > Data Analyst, Data Scientist, Senior Data Scientist. This dashboard shows Team, Subteam and individual member's performance. The performance is evaluated by respective managers of the subteams. And all the subteams are ranked by HR manager (Theodor). The beauty of this dashboard is that every month once the data is ready, the dashboard takes just a click to make for the new data.
