- The significance of these correlations was determined using a Student's
**t distribution**, with the degrees of freedom adjusted for autocorrelation at lag 1 using the method of Bretherton et al. (1999). (climateaudit.org) - Fitted parameter significance values were derived from the t-statistic of the parameter, i.e., its average divided by its standard deviation, which follows
**a t distribution**with n — p — 1 degrees of freedom, where n is the number of data points and p is the number of parameters (Chatterjee and Hadi, 2015). (frontiersin.org) - A more heavily tailed curve such as a Student's
**t distribution**with 6 degrees of freedom, say, looks much like a normal curve, and yet gives very different answers as to what is probable. (wattsupwiththat.com) - (see more)
