To fit this data to a log-normal distribution using scipy.stats.lognorm, use: s, loc, scale = stats.lognorm.fit (data, floc=0) Now suppose mu and sigma are the mean and standard deviation of the underlying normal distribution. To get the estimate of those values from this fit, use: Splet06. maj 2015 · It's the mean of the log of that random variable, which can be negative. Alternatively, if you really do mean that the fitted mean was negative: It might be possible for a shifted lognormal - like a lognormal distribution, but with an additional parameter representing a shift of the whole distribution. ghanaian symbols and their meaning
