Spherical error
In most treatments of OLS, the regressors (parameters of interest) in the design matrix are assumed to be fixed in repeated samples. This assumption is considered inappropriate for a predominantly nonexperimental science like econometrics. Instead, the assumptions of the Gauss–Markov theorem are stated conditional on . The dependent variable is assumed to be a linear function of the variables specified in the model… Web50th or 95th percentiles of horizontal, vertical and 3-D errors.

WebSpherical errors fails when we have either or both of: Heteroskedasticity: V [ϵi] ≠ V [ϵj] V [ ϵ i] ≠ V [ ϵ j]. Autocorrelation: Cov[ϵi,ϵj] ≠ 0 Cov [ ϵ i, ϵ j] ≠ 0 (for some i ≠ j i ≠ j ). Here’s what each of the three cases looks like in bivariate data.

Spherical errors occur when the optical power of the eye is either too large or too small to focus light on the retina. People with refractive error frequently have blurry vision. Farsightedness: When the optics are too weak for the length of the eyeball, one has hyperopia or farsightedness. This can arise from a … See more Refractive error, also known as refraction error, is a problem with focusing light accurately on the retina due to the shape of the eye and or cornea. The most common types of refractive error are near-sightedness See more Genetics There is evidence to suggest genetic predilection for refractive error. Individuals that have parents with certain refractive errors are more likely to have similar refractive errors.
