# hitconf

## Purpose

Calculate the keyword density.

## Syntax

returnedNum = hitconf(hitsNum, totalNum, fudgeNum)

returnedNum - type: int

hitsNum - type: int

totalNum - type: int

fudgeNum - type: int

## Returns

Returns a percent confidence as an integer between 0 and 100.

## Remarks

Useful as a way to convert density of hits in a file to a confidence
value. For example, if the total words in a file were 100 and there were
5 hits of a certain topic, then hitconf could compute a confidence for
that topic. The fudge factor typically varies from 3 to 20 or more. Empirically
you can determine what works best.

## Example

@CODE

G("confidence") = **hitconf**(5, 100, 17);
