Esempio:
Eseguire la regressione quadratica
per determinare i termini della formula
di regressione per i dati indicati qui
accanto. Seguentemente, utilizzare la
formula di regressione per stimare i
valori per
n (valore stimato di y) per xi
= 16 e per m (valore stimato di x) per
yi = 20.
Nel modo REG:

P 1.6 S 50 P 23.5 S
74 P 38.0 S 103 P 46.4 S
118 P 48.0 S
Coefficiente di regressione A =
–35,59856934
A X r r 1 =
Coefficiente di regressione B =

A X r r 2 =
Coefficiente di regressione C =

Precauzioni per l’introduzione dei dati
S S introduce lo stesso dato due volte.
•È possibile inoltre introdurre dati multipli dello stesso dato,
usando
A G. Ad esempio, per immettere il dato “20 e
30” cinque volte, premere 20
P 30 A G 5 S.
•I risultati sopraindicati possono essere ottenuti in
qualsiasi ordine, e non necessariamente nell’ordine
mostrato sopra.
Le precauzioni, quando si correggono i dati introdotti per
la deviazione standard, si applicano anche per i calcoli
di regressione.
