The broadband speed data I'm working with have all values over 3030Mbps placed into a >30 category. The distribution is thus truncated. This leads to the final column in the histographhistogram below being a catch-all for any values above this point. I've been advised to remove the final column. I'm tyring to develop a multilevel model which uses a variety of economic and socio economic varaibles at the postcode level and above.
Can anyone suggest a method to help me smooth out this spike in the distribution please? Is it possible to estimate the distribution of this variable above this cut off point?
Edit: After removing the final column of the distribution and log transforming the data, I still end up with a distribution like the histigram below. Can anyone advise any techniques on how I could better deal with this truncated distribution please?
