I need to find the distribution of data, which is from a retail chain network. No distribution fits the data
Have you tried transforming the data? Simulate multiple transformations and take the best approximation to a distribution amenable for statistical inference.
I need to find the distribution of data, which is from a retail chain network( demand of product across all stores). I tried to fit distribution using EasyFit (which has 82 distribution to check the best distributions) but no distribution fits the data. What can be done? Is there any way to find if the data distribution is a sum or convolution of multiple distribution? I have removed the spikes or seasonality or promotional data from the dataset but still no distribution fits.
