This note uses the established connection between the local-EM and EMS algorithms to explore methods for smoothing mismeasured data. Implementations of local-EM are developed for several forms of censored and/or mismeasured data and their connections with other methods explored.

We consider a problem of estimation for the telegrapher’s processon the line, say X(t), driven by a Poisson process with non constantrate. It turns out that the finite-dimensional law of the process X(t)is a solution to the telegraph equation with non constant coefficients.We give the explicit...
