p < 0 when using SVM for regression with R [closed]

https://stats.stackexchange.com/q/375998

It is still difficult to follow exactly what happens without the datafile.xlsx, but I could track down the error (it is in the C-code of the e1071 library) the parameter 'p' in the C-code refers to ...

y_{i}

(y_{i} - \overline{y})

in linear regression

https://stats.stackexchange.com/q/143059

\sum_{i = 1}^{n} (x_{i} - \overset{x}{ˉ}) = \sum_{i = 1}^{n} (x_{i}) - \sum_{i = 1}^{n} (\overset{x}{ˉ}) = \sum_{i = 1}^{n} (x_{i}) - n (\overset{x}{ˉ}) = 0

\sum_{i = 1}^{n} (x_{i} - \overset{x}{ˉ}) (y_{i} - \overset{y}{ˉ}) = \sum_{i = 1}^{n} (x_{i} - \overset{x}{ˉ}) (y_{i}) - \overset{y}{ˉ} \sum_{i = 1}^{n} (x_{i} - \overset{x}{ˉ}) = \sum_{i = 1}^{n} (x_{i} - \overset{x}{ˉ}) y_{i}

Understanding the random effect in linear mixed models (lme4, R) [duplicate]

lweek) rather than (P

g r u p p ∣ P

lweek) ... I think the answer is that they are simply ...

Find a set of sentences

Σ

such that the set of all models of

Σ

is countably infinite.

https://math.stackexchange.com/questions/515314/find-a-set-of-sentences-sigma-such-that-the-set-of-all-models-of-sigma-is

Well, according to your observations

Σ

is going to have to contain compound sentences (made up of connectives other than

\neg

). Perhaps the conceptually easiest way to ensure that the set ...

Implication arrows, turnstiles etc

Yes. Yes. Note that if the completeness theorem holds (this is the case in propositional or first-order logic), then

⊢

⊨

are essentially interchangeable, except that

M ⊢ a

Meanings of the terms “conjunct” and “disjunct” in a logic?

https://math.stackexchange.com/questions/340870/meanings-of-the-terms-conjunct-and-disjunct-in-a-logic

A = p \land q

A

is a conjunction of literals), and

B = r \lor s

B

is a disjunct of literals), then

p, q

are each conjuncts of

A

r, s

are each disjuncts of

B
