Abstract:
Logarithmic normal distribution is one of the important distributions in survival analysis. This paper uses the graphic method to study the maximum likelihood estimation based on random censored data by using EM algorithm, and then gives the graphic method to calculate the parameter estimations in Matlab. This method is simple and effective.[著者文摘]
