どこnは自由度数として知られています。 は、物理的な測定のように、未知の標準偏差の添加エラーでn+1の独立した測定値は、それぞれの与えられた未知の正規分布の値を意味して推定する際には、このディストリビューションを使用しています。あるいは、未知の標準偏差の正規分布の未知の平均、与えられたn+1サンプルを推定する際に.
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.
