07 Rg_In Finds the regression curve
using the natural logarithm
formula (natural logarithm
regression).
08 Rg_log Finds the regression curve
using the common logarithm
formula (common logarithm
regression).
09 Rg_ab
x
Finds the regression curve
using the exponential
function formula (exponential
regression-1).
10 Rg_ae
bx
Finds the regression curve
using the exponential
function formula (exponential
regression-2).
11 Rg_x
-1
Finds the regression curve
using the inverse function
formula (reciprocal regres-
sion).
12 Rg_ax
b
Finds the regression curve
using the power function
formula (power regression).
13 Rg_logistic Finds the regression curve
using the logistic logarithm
formula (logistic regression).
14 Rg_sin Finds the regression curve
using the sin regression
formula.
The calculator will fit a sin
curve for unequal, as well as
equal, spacing.
