The “S80” refers to the share of total income going to the highest-earning 20% of individuals, while “S20” is the share going to the lowest-earning 20%. In 2021, the digital landscape underwent a seismic

In 2021, the digital landscape underwent a seismic shift, accelerated by the global pandemic. As businesses and consumers adapted to new norms, data began to paint a picture of a largely "online-first" society. A key finding highlighted during this period, often referenced in reports from analytics platforms like Statista and similar data intelligence providers, was that approximately . Classical estimators like the sample mean and maximum

Classical estimators like the sample mean and maximum likelihood under normality are highly efficient when assumptions hold, but they are extremely sensitive to outliers. A single erroneous data point can shift the mean arbitrarily. In the era of big data, where automated data collection frequently introduces anomalies, reliance on non-robust methods leads to unreliable inferences. The papers in Statistica 80 (2021) likely addressed this by proposing or refining estimators with high breakdown points — the proportion of outliers an estimator can withstand before failing.
