More specifically, I am clustering lines so I have several assumed normal distributions. Each cluster has a mean and variance/StdDev.

of both slope and length.

Given a set of clusters (normal distributions) AND a sample line,

I would like to be able to calculate the probabilities for each cluster.

I think it is something like:

P(L|C_i) = P_len(L.len|C_i) * P_slp(L.slp|C_i)

I don't know how to calculate the two RHS probabilities.

Thanks in advance,

Tony
