- FitLog[ <List of Points> ]
- Calculates the logarithmic regression curve.
- Example:
FitLog[{(ℯ, 1), (ℯ^2, 4)}]
yields -2 + 3 ln(x).
CAS Syntax
- FitLog[ <List of Points> ]
- Calculates the logarithmic regression curve.
- Example:
FitLog[{(ℯ, 1), (ℯ^2, 4)}]
yields 3 ln(x) - 2.
Note:
- Euler's number ℯ can be obtained by pressing ALT + e.
- See also FitExp Command, FitPoly Command, FitPow Command and FitSin Command.
