RE: “EFFICIENT ESTIMATION OF SMOOTH DISTRIBUTIONS FROM COARSELY GROUPED DATA”

In the article “Efficient Estimation of Smooth Distributions From Coarsely Grouped Data” by Rizzi et al. (1), there was an error in the R code. On page 146, in the first line of R code, la2 should be replaced with lambda so that the computation of weights read “w < −c(1/mu, rep(lambda, nx − deg)).” The code has been updated in the most recent version of this article.

The authors regret this error.
