WebFeb 1, 2024 · I'm having the exact same problem as you. What i've found googling about it is that you need to provide the empirical moments function and the theoretical moments function, for Pearson III distribution, when using fitdist from fitdistrplus..

This is, if you have a sample ( x 1,..., x n) ∼ log-Pearson III, then ( log ( x 1),..., log ( x n)) ∼ Pearson III which is also a shifted-gamma and this is easier to estimate.

WebNov 28, 2014 · It helps to work from an example. Let’s invent one by taking the first 50 randomly generated Pearson type III variates from the test at the bottom of the first sheet in PearsonIII.xlsm. To make things a little more realistic, introduce a bit of “noise” by rounding them off to three significant figures, so they look like this: 1820. The Pearson types are characterized by two quantities, commonly referred to as β 1 and β 2. The first is the square of the skewness: where γ 1 is the skewness, or third standardized moment. The second is the traditional kurtosis, or fourth standardized moment: β 2 = γ 2 + 3. See more The Pearson distribution is a family of continuous probability distributions.
