Abstract: The parameter estimation of linear exponential distribution based on truncated and censored data model is studied. The maximum likelihood estimation method and EM algorithm are respectively used to estimate the unknown parameters, and stochastic simulations are carried out. It is found that the parameter estimation obtained by maximum likelihood estimation is similar to that obtained by EM algorithm, but the convergence speed of EM algorithm is faster.
