Weibull Fit Algorithms

Windographer incorporates four Weibull fit algorithms:

Weibull Fit AlgorithmDescription
Maximum Likelihood AlgorithmUses Stevens and Smulders equations in an iterative fashion.
Least Squares AlgorithmTransforms axes of the cumulative distribution function, then uses linear least squares to determine Weibull parameters.
WAsP AlgorithmFinds Weibull parameters that match the observed mean wind power density and proportion of wind speeds above mean.
Openwind AlgorithmFinds Weibull parameters that match the observed mean wind speed and mean wind power density.

You can choose your preferred Weibull fit algorithm in Tools > Options > General.

The Wind Speed Distribution window is the only part of Windographer that reports the results of other Weibull algorithms.
