    What are you saying by 'the initial positions of the clusters'?

    Did you mean to say 'which observations fall into which clusters'?

    For example if you have 5 observations and decide to make k=2, allocate the observations randomly into 2 clusters, calculate the means and min distances to re-allocate.

    The initial allocation won't have a bearing on the end result for a fixed k. Although it may change the number of iterations requird to reach the final clustering.
