I'm just trying to analyze soma data using distribution fiting tool of Matalab. I want to find the mean by fiting some curve types like Log, exponential, Burr, etc. I manually calculated the mean of my data set and compared with the mean produced by the Matlab relative to various curve types. Sometimes though the curve is fitted well, the means are different. As per manual calculation mean is 0.588175. The mean values proposed for various types of curve fiting options are mentioned below.
- Exponential – 0.588175
- Bur – 1.06174
- Log-Logistic – 0.686126
How can I find the best fitting curve for my dataset? Further I extracted the [x,f(x)] data for the fitted curve from the matalab and poltt the curve in excel. Though the curve is ok the mean calculated from these values are different to the mean produced by the matlab. As an example Bur distribution indicates a value of 1.06174 for mean, but the extracted data gives a mean arround 0.5.
Your valuable comments are highly appreciated since I am still new to this tool.
