Unfortunately, a designation of a region like "western Puerto Rico" means so many different things to so many different people, that I disbelieve its utility. With the definition you quote, we should have a 100% chance of precipitation almost every day. --FF841A0334127EDA335D19E4 Content-Type: text/x-vcard; charset=us-ascii; name="rabeldin.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Richard A.

Re: basic stats question
This is a multi-part message in MIME format. --D6CAE5CBE7F2826036C27891 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit The suits and ranks of cards in a bridge deck certainly can be presented as independent sample spaces which we use as components of a cartesian product. Whether one does so or not is a matter of choice. I am on record as favoring the presentation as the cartesian product. Even the sample mean and variance can be seen this way, in fact, every vector valued random variable can be cast in the form of a random vector from a cartesian product. My point is that if we introduce independence as an attribute of sample spaces which we proceed to study as one, we can better motivate the idea of independent random variables and independent events. --D6CAE5CBE7F2826036C27891 Content-Type: text/x-vcard; charset=us-ascii; name="rabeldin.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Richard A.

Re: probability definition
This is a multi-part message in MIME format. --3C6331B8C260BF767681A8B3 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit The "definition" via axioms provides a mathematical structure that we interpret either as "relative frequency" or as "degrees of belief". Indeed, I think that any phenomenon which satisfies the axioms can serve as an "interpretation". As they say, "If it walks like a duck, ...". As far as the probability of rain tomorrow, I always explained to my students that the language is so imprecise that the numerical value has only rhetorical utility. We need to know: 1) How much rain in cm. ? 2) In which locations? 3) During what time span? Does 70% probability mean that it rains in 70% of the locations or 70% of the time or what? Your instincts are correct. That example is severely flawed because we have not made the experiment clear. Continue to question the simple examples. You will learn from it. --3C6331B8C260BF767681A8B3 Content-Type: text/x-vcard; charset=us-ascii; name="rabeldin.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Richard A.

Re: Bg/Time data extrapolation?
This is a multi-part message in MIME format. --8BC3F97AC4614F6838A310AE Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Given the assumption that blood glucose levels have a circadian rhythm, you might think of a closed orbit as a model. If you had more than one 24-hour period of data, you could get started. It talkes all of your 2-hour interval observations to get the equivalent of ONE observation on the orbit. To understand the impact of food intake and other variables, a very extensive study would be required. On the other hand, I would hazard a guess that someone has already done this. Try http://www.Search4science.com/ for a search with terms like glucose level and circadian rhythm. Good luck. --8BC3F97AC4614F6838A310AE Content-Type: text/x-vcard; charset=us-ascii; name="rabeldin.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Richard A.
