Italian term or phrase: g.d.l.
Can anyone tell me what "g.d.l." might mean in the context of statistics, cluster analysis, or the "Fisher value" (I think that would be the translation of "statistica F di Fisher"). It's the header of a column in a table where the other headings are "Variabili", "Fisher", Valore test", "Prob.", "Media" e "Dev. Std". Thanks, Sarah.

df (degrees of freedom) gradi di libertà

Explanation:
http://it.wikipedia.org/wiki/Gradi_di_libert%C3%A0_(statistica)
I gradi di libertà di una variabile aleatoria o di un statistica in genere, esprimono il numero di dati effettivamente disponibili per valutare la quantità d' informazione contenuta nella statistica. Infatti, quando un dato non è indipendente, l'informazione che esso fornisce è già contenuta implicitamente negli altri. È possibile quindi calcolare le statistiche utilizzando soltanto il numero di osservazioni indipendenti, consentendo in questo modo di ottenere una maggiore precisione nei risultati.

Il concetto di gradi libertà venne introdotto in statistica da Ronald Fisher negli anni 1920.

Diverse variabili casuali (t di Student, F di Snedecor, Chi Quadrato e Chi Quadrato non centrale, v.c. di Wishart e altre) hanno parametri detti comunemente "gradi di libertà".
