Introducing 2SLS: Why the two-stage approach matters In empirical research, endogeneity often undermines straightforward regression analysis. When an explanatory variable is correlated with the error term, ordinary least squares (OLS) can produce biased and inconsistent estimates. The two-stage least squares, commonly abbreviated as 2SLS, offers a robust framework to address this issue by using instrumental…

Gas purging is a fundamental process across a range of sectors, from sensitive electronics manufacture to large-scale pipeline maintenance. The aim is simple in principle—replace a process chamber, pipework or system’s original atmosphere with an inert or otherwise controlled gas to reduce the risk of unwanted reactions, contamination or ignition. In practice, the practice of…

The car industry relies on a deceptively simple idea that powers the smooth, predictable motion we take for granted: the differential. At its core, the differential is a specialised gearing arrangement that allows wheels to spin at different speeds while still delivering power from the engine. This is essential when a vehicle turns, because the…
