摘要

It is well known that in many practical applications, the data follow a log-normal distribution instead of a normal distribution. The log-normal model is commonly used in medicine and economics, where the basic process under consideration leads to a skewed distribution. One can often use a log-transformation to normalize the distribution of the original data. Even though the failure rate of the normal distribution is increasing, the failure rate of the log-normal distribution increases initially to a maximum and then decreases to zero as time approaches infinity. On the other hand, the mean residual life function (MRLF) exhibits a reverse behavior. It decreases initially and then increases. The authors of this paper deal with the monotonicity of the failure rate and the MRLF of a generalized log-normal distribution proposed by Chen (Ref. 1). This parametric family of distribution includes the log-normal distribution as a special case. The generalization is a three-parameter family which has the feature that one of the parameters can be regarded as playing the role of choosing a suitable transformation. Chen (Ref. 1) studied the parameter estimation and goodness-of-fit tests for fitting the generalized log-normal distribution to the electrical appliance data.
