# What dose the symbol Pr mean?

hello everyone,I'm from china,and i need your help.there are some words in a paper as follows :

The potential functions $$V_{i}$$ are defined as the negative log posterior of the two segments’ ordinal depths conditioned on the curve cues, weighted by the curve length |Ci|

And probably the symbol Pr is short for Posterior.
but what dose the Pr mean?
thank you very much!

Is it in the "The 2.1-D Sketch" paper again? I don't seem to find that symbol in there... Where exactly is it?

could you tell me how to understand Pr( $${d_{i}}^{M}_{i=1})$$

I'm very glad to meet you again.you're so friendly.

My guess is that Pr just denotes the probability function. That is, $$Pr(\{d_i\}_{i=1}^N)$$ denotes the probability that $$\{d_i\}_{i=1}^N$$ is assumed.
