And the quiz streak continues.

#StatisticsChallenge (23/50)

Just one of those days that one is too busy to do much more.

Summary:

Quiz: 1

#StatisticsChallenge (22/50)

Had a situation today where I could use the Kullback–Leibler divergence to compare differences of bus routes that have potential alternate routes. Though it might be a bit overkill.

Quiz: 1

#StatisticsChallenge (21/50)

Continued and finished the homework from day 19.

The one problem dealt with showing that the Kullback–Leibler divergence is greater equal to zero with using the Jensen's inequality.

The other problem dealt with showing the moment-generating function for the gamma distribution.

Homework: 2

#StatisticsChallenge (20/50)

Dealt with the step function in class. The image defines a step function. To my understanding it is right continuous, so wouldn't it be an over estimate for functions that are $f'(x) < 0$ and thus in such a case the ceiling function would be better? Or does it not matter?

#statistics #math

A #statistics question:

Let's say we have a symmetric distribution around /(x=\alpha/). In this case is the expected value /(/mathbb{E}(X)=\alpha/)?

If the symmetric distribution is /(f(x)/), then what would be the median? Is it /(f(/alpha)/) or is it just /(/alpha/).

If anyone is interested, I participated in managing a talk about #privacy in a fishbowl style. The talk will be in German only and starts at 18:00 UTC+01

#StatisticsChallenge (19/50)

First day that I did practical work. Only got through 1 of 3 homework problems. Got stuck on the second problem trying to prove why Kullback-Leibler divergence is greater equal to 0 with using the Jensen inequality. The case that it is equal to zero is easy to prove, the other one is causing the progress.

Always love it when the maths aligns so lovely, especially the case of the \(e^x\) and the \(\Gamma(x)\) function.
