Eksempelsætninger

It is emphasis on contravariance rule, covariance rule and closed-behavior rule that generic-special relation must abide in this paper.

Det er betoningen af contravariance-reglen, kovariansreglen og reglen om lukket opførsel, at det generiske-specifikke forhold skal overholde i dette papir.

The covariance between two variables can help determine the relationship between them.

Kovariansen mellem to variabler kan hjælpe med at bestemme forholdet mellem dem.

In statistics, covariance measures how two variables change together.

Inden for statistik måler kovarians, hvordan to variabler ændrer sig sammen.

Positive covariance indicates that the variables tend to move in the same direction.

Positiv kovarians indikerer, at variablerne har tendens til at bevæge sig i samme retning.

Negative covariance suggests that the variables move in opposite directions.

Negativ kovarians antyder, at variablerne bevæger sig i modsatte retninger.

Covariance is used in portfolio theory to measure the relationship between asset returns.

Kovarians bruges i porteføljeteori til at måle forholdet mellem afkast på aktiver.

The covariance matrix summarizes the variances and covariances of multiple variables.

Kovariansmatricen opsummerer varianserne og kovarianserne for flere variabler.

Covariance is an important concept in multivariate analysis and machine learning.

Kovarians er et vigtigt koncept i multivariabelanalyse og maskinlæring.

Researchers often analyze covariance to understand the dependency between different factors.

Forskere analyserer ofte kovarians for at forstå afhængigheden mellem forskellige faktorer.

Covariance plays a crucial role in financial modeling and risk management.

Kovarians spiller en afgørende rolle i finansiel modellering og risikostyring.

Understanding covariance can help in predicting future trends and making informed decisions.

At forstå kovarians kan hjælpe med at forudsige fremtidige tendenser og træffe informerede beslutninger.

Virkelige Eksempler

We have the covariance of these two random variables.

Vi har kovariansen for disse to stokastiske variable.

And then we do the covariance between the vertical movements of wind and the concentration of gas.

Og så beregner vi kovariansen mellem de vertikale vindbevægelser og gaskoncentrationen.

It's called an eddy covariance tower.

Det kaldes et turbulenskovarians-tårn.

Now we don't know the entire covariance, we only have one sample here of this random variable.

Nu ved vi ikke hele kovariansen, vi har kun én stikprøve af denne stokastiske variable her.

Well, you could view this as the covariance of X with X. But we've actually already seen this.

Tja, du kan se det som kovariansen af X med X. Men vi har faktisk allerede set det.

The covariance of a random variable with itself is really just the variance of that random variable.

Kovariansen af en stokastisk variabel med sig selv er i virkeligheden bare variansen af den stokastiske variabel.

And the degree to which they do it together will tell you the magnitude of the covariance.

Og i hvilken grad de gør det sammen, vil fortælle dig størrelsen på kovariansen.

Hopefully that gives you a little bit of intuition about what the covariance is trying to tell us.

Forhåbentlig giver det dig en lille smule intuition om, hvad kovariansen forsøger at fortælle os.

I want to connect to this definition of covariance to everything we've been doing with least squared regression.

Jeg vil forbinde denne definition af kovarians til alt, hvad vi har lavet med mindst kvadraters regression.

So this whole video, I'm just going to rewrite this definition of covariance right over here.

Så i hele denne video vil jeg bare skrive denne definition af kovarians her.
