Let be a finite measure on algebra , for and (i.e. ). Show that . Since ,

## Probability Foundations – Problem (38/365)

Let be a finitely additive measure on an algebra , and let be pairwise disjoint and satisfy . Then show that .

## Probability Foundations – Problem (37/365)

A problem similar to the previous post. Let be a countable set and a collection of all its subsets. Put if is finite and if is inifinite. Show that the set function is finitely additive but not countable additive. To … Continue reading

## Probability Foundations – Problem (36/365)

I did say it would be one post a day and it already looks like i’ll only achieve it as an expectation of posts every day. So, let me catch up first by solving more problems. This time from chapter … Continue reading

## Expectation Maximization – Link (35/365)

Dan Piponi has written up a simple to follow derivation of the Expectation-Maximization algorithm. It give a very practical derivation of the algorithm which also makes it easy to remember. What it clarifies for me is the step in the … Continue reading
