I DON'T KNOW sorry * * * * * Three dimensional shapes, regular polyhedra.
What is gaussian distribution and what is its significance in least squares analysis?
From a technical perspective, alternative characterizations are possible, for example: The normal distribution is the only absolutely continuous distribution all of whose cumulants beyond the first two (i.e. other than the mean and variance) are zero. For a given mean and variance, the corresponding normal distribution is the continuous distribution with the maximum entropy. In order to make statistical tests on the results it is necessary to make assumptions about the nature of the experimental errors. A common (but not necessary) assumption is that the errors belong to a Normal distribution. The central limit theorem supports the idea that this is a good approximation in many cases. The Gauss-Markov theorem. In a linear model in which the errors have expectation zero conditional on the independent variables, are uncorrelated and have equal variances, the best linear unbiased estimator of any linear combination of the observations, is its least-squares estimator. "Best" means that the least squares estimators of the parameters have minimum variance. The assumption of equal variance is valid when the errors all belong to the same distribution. In a linear model, if the errors belong to a Normal distribution the least squares estimators are also the maximum likelihood estimators. However, if the errors are not normally distributed, a central limit theorem often nonetheless implies that the parameter estimates will be approximately normally distributed so long as the sample is reasonably large. For this reason, given the important property that the error mean is independent of the independent variables, the distribution of the error term is not an important issue in regression analysis. Specifically, it is not typically important whether the error term follows a normal distribution. In a least squares calculation with unit weights, or in linear regression, the variance on the jth parameter, denoted , is usually estimated with where the true residual variance σ2 is replaced by an estimate based on the minimised value of the sum of squares objective function S. The denominator, n-m, is the statistical degrees of freedom; see effective degrees of freedom for generalizations. Confidence limits can be found if the probability distribution of the parameters is known, or an asymptotic approximation is made, or assumed. Likewise statistical tests on the residuals can be made if the probability distribution of the residuals is known or assumed. The probability distribution of any linear combination of the dependent variables can be derived if the probability distribution of experimental errors is known or assumed. Inference is particularly straightforward if the errors are assumed to follow a normal distribution, which implies that the parameter estimates and residuals will also be normally distributed conditional on the values of the independent variables.
What happens if a value falls below the mean 2 standard deviation when the probability to belong to the distribution is lower than 0.05?
Nothing actually happens! You just get a value that is very unlikely but still possible. That it is possible is evidenced by the fact that the value was observed.
What rational number does 100 belong to?
It is 100, which does not belong to any other number!
Whose distribution belong exponential family?
Poisson distribution or geometric distribution
What category do points lines and planes belong too?
They are basic geometric concepts.
What geometric group do the platonic solids belong to?
I DON'T KNOW sorry * * * * * Three dimensional shapes, regular polyhedra.
What organ system does the ventricle belong to?
The Ventricle belongs to the Cardiovascular System; which regulates blood flow and oxygen distribution.
What one does not belong circle square triangle rectangle sphere octagon?
The correct answer is Sphere. All of these are geometric shapes, however only the sphere is a 3 dimensional one.
Does crystals of a mineral come always in the same size?
The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
What country does American express 3790 belong?
3790 is part of the American Express gift card scheme. The point of distribution is US based. However, there may be vendors selling the gift cards from other locations.
Why are US films the best?
They aren't. The reason they are the most watched is because the US has a strangle hold over the distribution of movies meaning that the choice is limited. makers of films that do not belong to the Hollywood clique have a hard time competing.
If you do not belong to majority of the population were do you belong?
You belong to a minority.
What set or series like the Itsu do the Herald of Green Orange and Purple light belong to in Yu-Gi-Oh?
They belong to the Enemy of Justice set, and are amongst the first of the very geometric, crystalline 'synthetic angel' cards. They share a theme with cards like Majestic Mech - Ohka, Banisher of the Radiance and Meltiel - Sage of the Sky Herald of Orange Light in The Duelist Genesis, and Herald of Perfection in The Shining Darkness, also share the theme.

What state does the Sturt's desert pea belong to?
Sturt's Desert Pea does not belong exclusively to any state. It is the official floral emblem of South Australia. However, it is not limited to that state alone. Sturt's desert pea is found in arid woodlands and bushland, open plains and desert areas of central Australia, spreading in its distribution through all mainland states except Victoria.
