Am I right that, normally >people use *pdf* for "probability density function" and *PDF* for >"probability distribution function"? No, I don't think that is the convention. I would take either "pdf" or "PDF" as meaning "probability density function". The usual abbreviation for the distribuiton function is "cdf" or "CDF" - for "cumulative distribution function". I think it is good practice to always put in the "cumulative", since many people will have a tendency to misinterpert "distribution function" as meaning "density function".
