These statistics\ninclude class frequencies and central moments of order one up\nto four. The log-density is modelled using a linear combination\nof penalised B-splines. The multinomial log-likelihood\ninvolving the frequencies adds up to a roughness penalty based\non the differences in the coefficients of neighbouring\nB-splines and the log of a root-n approximation of the sampling\ndensity of the observed vector of central moments in each\nclass. The so-obtained penalized log-likelihood is maximized\nusing the EM algorithm to get an estimate of the spline\nparameters and, consequently, of the variable density and\nrelated quantities such as quantiles, see Lambert, P.
