WebLater in the article, you’ll see the some of the more frequently used ones. Let's take a look at some of the terminology and notation used. The result of a point estimation of a parameter is a single value, usually referred to as the estimator, and it will usually have the same notation as the population parameter it represents plus a hat '^'. Webthe population at time n 0. Then, X n+1 = X n Y n+1 + 1, where the conditional distribution of Y n+1 given X n = kis a binomial random variable with parameters (k;c(k)). We assume that lim k!1 kc(k) = ˆ exists. If ˆ<1 the process is transient with speed 1 ˆ(so yes a single migrant per generation may rescue a dying population!) and if ˆ>1
