### Generating M/U Probabilities in Fellegi-Sunter Record Linkage

I'm working on merging records from several databases that cover the same entities, but share no reliably deterministic fields, leaving us with fields such as name and address to resolve identity. In ...

### When to use the raw dataset as opposed to a transformed dataset for computing divergence?

Let us assume I have a set of observations: Dataset 1: Raw $A = [a_1,a_2,a_3,a_4,...]$ $B = [b_1,b_2,b_3,b_4,...]$ One assumptions before I proceed: Range of the values that the random variable ...

### How to convert multiple ranking scores into a probability distribution?

I would like to create a topic distribution for a document. The current model I am trying to implement is: for each sentence in the document, I am getting a topic assignment with a score, e.g. "1st ...

### Detecting fishy data

Just a little thought I've been having. If we rolled a fair dice 60 times, and got 60 sixes in a row, we would (wrongly?) definitely assume that something fishy's going on. Is there any statistical ...

### Computing probability of proportions of (possibly) overlapping sets

Consider $n$ fixed subsets of a finite universe $U$: $A,B,C,D,\ldots$ Then let $Coll$ be the collection of sets we get from the closure of the set $\{U,A,B,C,D, \ldots\}$ under the operations ...

### Calculating the probability that demographic trends happened by chance

I ran an ad campaign on Facebook and I have impressions (ad-views), clicks, and sign-ups broken down by gender and age. Certain demographics have a higher rate of clicks and sign-ups when compared to ...
Lets say we have $T$ tags and $N$ articles and lets say that for each tag $t_{i}$ we know that it has tagged $n_{i}$ articles. Meaning that, frequency($t_{i}$)=$n_{i}$. Given the above information ...
