wo n ist als die Anzahl der Freiheitsgrade' bekannt. Diese Verteilung wird verwendet, wenn die Schätzung der bedeutet von einem unbekannten normal verteilt Wert angegeben n+1 unabhängigen Messungen mit jeweils additive Fehler unbekannter Standardabweichung, wie in physikalischen Messungen. Oder alternativ, bei der Schätzung der unbekannten Mittelwert einer Normalverteilung mit unbekannter Standardabweichung, da n+1 Proben .
Original:
where n is known as the number of degrees of freedom. This distribution is used when estimating the mean of an unknown normally distributed value given n+1 independent measurements, each with additive errors of unknown standard deviation, as in physical measurements. Or, alternatively, when estimating the unknown mean of a normal distribution with unknown standard deviation, given n+1 samples.
