Description
  • Využití lineárního regresního modelu při statistických analýzách není zcela universální, musí být splněna řada předpokladů.Náhodné chyby se musí řídit normálním rozložení pravděpodobností a jejich rozptyly musí být konstantní.Pokud tyto předpoklady splněny nejsou, je obtížné odvodit rozdělení pravděpodobností odhadu regresních koeficientů. Metodou, která pomáhá řešit tuto situaci, je bootstrapový resampling.Aplikace této metody je popsána v článku. (cs)
  • The linear regression model is one of the most important methods of statistical inference having wide practical use. This method is unfortunately used in the universal way without examining its assumptions. The essential assumption is that random errors have the normal distribution and their variances are constant values. The properties of the estimates obtained in this way are well known. In case when random errors are not normally distributed or their variances are not constant values (i.e., it changes depending on values of independent variable) it is seldom possible to derive the properties of distribution of regression coefficients estimates. The asymptotical properties of these estimates based on central limit theorem are usually assigned. They correspond with reality only in cases of large random samples. In reality we have small sample sizes so that the results obtained by these methods are not reliable enough. Other approximations can be used to determine the properties of estimates in some c
