Excel is often poorly regarded as a platform for regression analysis. The regression add-in in its Analysis Toolpak has not changed since it was introduced in 1995, and it was a flawed design even back then. (See this link for a discussion.)

Ecommerce sites generate tons of web server log data which can provide valuable insights through analysis. For example, if we know which users are more likely to buy a product, we can perform targeted marketing, improve relevant product placement on our site and lift conversion rates.

All these buzz words, coupled with misplaced applications of data science have turned it into a fairly nebulous concept. Which is a problem.
In facilitating my data science workshops I've realized there are two main groups of audiences and learners.…
Luxury car manufacturer, BMW in the year 2017 faced production stoppage due to Bosche’s inability to supply steering gears. This issue which lasted for about a week caused the German manufacturer to lose €400-€500m, aside from impacting the production of further models.
This example clearly shows how a small inefficiency in the supply chain can have an overall negative impact on the productivity of organizations. A large number of companies which are a…Continue
