Jul 8, 2020 · The " r value" is a common way to indicate a correlation value. More specifically, it refers to the (sample) Pearson correlation, or Pearson's r. The "sample" note is to emphasize that you can only claim the correlation for the data you have, and you must be cautious in making larger claims beyond your data. This is the E notation form of Scientific notation, a shorthand for writing large or small numbers with fewer characters. As others said, your example means 689 x 10 12. It might also appear as 689e12. "e-" is used to represent numbers less than 1: .00000689 = 6.89e-6. Shorthand for "689 times 10 to the 12th power".

The MSE either assesses the quality of a predictor (i.e., a function mapping arbitrary inputs to a sample of values of some random variable), or of an estimator (i.e., a mathematical function mapping a sample of data to an estimate of a parameter of the population from which the data is sampled). In the context of prediction, …

Clear communication is key.) If there is one, I have never used it.

Intuitively, it means that for every x ∈ R x ∈ R, the function f will give back a value f(x) ∈ R f ( x) ∈ R. For example, a function f(x) = 1/x f ( x) = 1 / x is only defined for those x ∈ R x ∈ R Real Numbers R R that are different from 0 0, so you should write f: R/{0} → R f: R / { 0 } → R.
