Is there a program available online that can detect statistically significant higher incidence of a specific root (שרש), and/or of a specific sequence of letters, in a specific portion of *Tanach*. For example, one might input the root שוב, or, alternatively, the sequence of letters שב, to determine if their incidence in *Parshath Miketz* is abnormally high.

though I'm looking for something that would provide, as well, some statistical information - if only to show that a higher incidence in a specific portion is somewhat anomalous.)
