I have a very small set of data. Usually 3 points, sometimes 4.
Best fit is a logarithmic equation y=m*Ln(x)+b
How can I obtain m and b?

Logarithmic regression is a statistical method used to model a relationship between two variables where one variable increases at a logarithmic rate while the other variable remains constant. It is commonly used to analyze data that follows a non-linear trend.
Logarithmic regression is used when the relationship between the variables being analyzed is not linear, but rather follows a curved trend. It is often used in fields such as economics, biology, and environmental science to analyze data that exhibits exponential growth or decay.
The calculation for logarithmic regression involves taking the natural logarithm of the dependent variable and using a linear regression model to find the best-fit line. This can be done using statistical software or by hand using the appropriate formulas.
Logarithmic regression allows for the analysis of data that follows a non-linear trend, which cannot be accurately represented using traditional linear regression. It also has the advantage of being able to handle data with a wide range of values and is less sensitive to outliers compared to other regression methods.
Logarithmic regression assumes that the relationship between the variables being analyzed is logarithmic, which may not always be the case. It also requires a large sample size and may not be suitable for data that exhibits a weak relationship between the variables. Additionally, the interpretation of the results can be more complex than with linear regression.
