Hello, Yes, there is even an old discussion on this on r-devel, dated August, 10 2013. See [1]. [1] https://r-project.markmail.org/search/?q=broken-link-in-docs-for-Binormial-functions#query:broken-link-in-docs-for-Binormial-functions+page:1+mid:rf6tbiokcdyai6el+state:results Hope this he

Thank you Peter and Spencer. That clears things up. Also since no one responded the second part of my question, I'm still wondering if it was noted that there is a hyperlink in the dbinom help file (?dbinom) that isn't directing correctly? Stefan On Fri, Mar 15, 2019, 07:37 peter dalgaard, wrote

Stefan--- Under the measure-theoretic approach to probability, discrete & continuous probability densities follow the same underlying mathematical principles. Check any text on measure-theoretic probability theory. ---JFL Stefan Schreiber Sent by: "R-help" 03/14/2019 08:43 PM To r-help@
