March 23, 2022 -
I just had a discussion with a colleague regarding reporting of results from rank-order correlation using Spearman’s method, which yields ρ, or rho. Rho can be estimated from a bivariate association between two independent values measured in a sample. The sample is intended to represent the population it was sampled from - should or should not then the sample estimate be reported with a hat (ρ̂ )?

I vote for hatting it because I have always been taught and have always read that estimates gets a hat to distinguish from the actual value, unless they have their own symbol for a specific purpose (a bit like s being a sample estimate of sigma). Less important if you are writing up simple results (I would simply use Rho in that case), more important in textbooks or anything where you are using formulas to prove something or show something. Maybe someone disagrees, though.

While I agree that the hat is technically correct, when reported as a number I don't think there's much confusion: if I were to report that ρ=0.43 I don't think readers are going to get confused and think I'm talking about the population value instead of the sample. Hats also won't always typeset well, and might mess up any future NLP run on your reporting - those shouldn't be problems in 2022, but they still are. I would probably report it without that hat for simplicity's sake, even though I think the hat is technically correct.

May 9, 2021 - So the triad lasts for the whole measure; it should sound for 4 beats, though what’s notated and what’s possible doesn’t always mean the same thing. It should be doable in this case. The rest and the two quarters are the melody line. If the chord had stems, they’d go down to signify that it’s a different line.

p = probability value. The specific meaning depends on context. In geometric and binomial probability distributions, p is the probability of “success” (defined here in Chapter 6) on any one trial and q = (1−p) is the probability of “failure” (the only other possibility) on any one trial.

Stats: Estimating the Proportion
When you're computing E, I suggest that you find the sample proportion, p hat, and save it to P on the calculator. This way, you can find q as (1-p). Do NOT round the value for p hat and use the rounded value in the calculations. This will lead to error. Once you have computed E, I suggest ...
