Kvantileide

Kvantileide is a term found in some Estonian-language statistical texts referring to ideas or methods grounded in quantiles. A quantile divides a distribution into regions containing equal probabilities; common examples are quartiles (four parts), deciles (ten parts), and percentiles (hundred parts). The compound noun kvantileide denotes quantile-based concepts or approaches in data analysis.

In practice, kvantileide-based approaches use sample quantiles computed from data using order statistics. The calculation can be exact for small samples or approximate for large datasets via straightforward algorithms that sort data or use online updating schemes.

Applications of kvantileide concepts include descriptive statistics, exploratory data analysis, outlier detection with the interquartile range, robust data summarization, and as a basis for quantile-based predictive tools such as quantile regression.

Terminological note: kvantileide is not standard in English-language statistics; it is a regional or translation-based term that roughly equates to a quantile-based concept. Related terms include quantile, quartile, percentile, decile, interquartile range, and quantile regression.
