select a statistical calculation type.
(1-Variable)

(y=a+bx)
Paired-variable ([, \), linear regression
(y=a+bx+cx
2
)
Paired-variable ([, \), quadratic regression
(y=a+b㺃ln(x))
Paired-variable ([, \), logarithmic regression
(y=a㺃H^(bx))
Paired-variable ([, \), H exponential regression
(y=a㺃b^x)
Paired-variable ([, \), DE exponential regression
(y=a㺃x^b)
Paired-variable ([, \), power regression
(y=a+b/x)
Paired-variable ([, \), inverse regression
• Performing any of the above key operations displays the Statistics
Editor.
Note: When you want to change the calculation type after entering the
Statistics Mode, perform the key operation (Select Type) to display
the calculation type selection screen.
Inputting Data with Statistics Editor

single variable and frequency ([, Freq), paired-variable ([, \), paired-
variable and frequency ([, \, Freq). The number of data rows that can be
input depends on the number of columns: 160 rows for one column, 80
rows for two columns, 53 rows for three columns.
