Deutsch: Darstellung des w:de:Bootstrapping-Verfahrens. Aus einer Population wird eine Stichprobe gezogen. Aus dieser Stichprobe werden durch Ziehen mit Zurücklegen Stichprobenwiederholungen gezogen (orange). Datenpunkte welche mehrfach gezogen wurden (circa 26,4% bei großen Stichproben) sind rot und leicht versetzt doppelt gezeichnet. Aus den Stichprobenwiederholungen wird jeweils die Statistik berechnet, wodurch ein Histogramm zum Schätzen der Verteilung von berechnet werden kann.
English: A sample is drawn from a population. From this sample, resamples are generated by drawing with replacement (orange). Data points that were drawn more than once (which happens for approx. 26.4% of data points) are shown in red and slightly offsetted. From the resamples, the statistic is calculated and, therefore, a histogram can be calculated to estimate the distribution of . |
