WebThe data CDF and lines of best t can be easily plotted plot(m_pl) lines(m_pl,col=2) lines(m_ln,col=3) lines(m_pois,col=4) to obtain gure1. It clear that the Poisson distribution is not appropriate for this data set. However, the log-normal and power law distribution both provide reasonable ts to the data. 1.1 Parameter uncertainty WebConstruct the power law distribution object. In this case, your data is discrete, so use the discrete version of the class data <- c (100, 100, 10, 10, 10 ...) data_pl <- displ$new (data) Estimate the x m i n and the exponent α of the power law, … methodology company
