When errors is a ar (1) time series, we studied the quasi-likelihoodequation for the semiparametric model, and investigated the existence of quasi-maximum likelihood estimators.
By applying the method of reliability statistics, a parameter iteration of maximum likelihoodequation is set up for MIS software with an operation life submitting to minimum distribution.

By figuring out how many Earth-like planets exist, we'll have a much better idea about some key variables in the Drake equation, which attempts to describe the likelihood of finding intelligent life.
