English term or phrase: heteroskedasticity
Definition from Investopedia:
In statistics, heteroskedasticity (or heteroscedasticity) happens when the standard errors of a variable, monitored over a specific amount of time, are non-constant. With heteroskedasticity, the tell-tale sign upon visual inspection of the residual errors is that they will tend to fan out over time

Example sentence(s):
  • Most real world data will probably be heteroskedastic. However, one can still use ordinary least squares without correcting for heteroskedasticity because if the sample size is large enough, the variance of the least squares estimator may still be sufficiently small to obtain precise estimates. Methods for Detecting and Resolving...
  • Heteroskedasticity can also occur if there are subpopulation differences or other interaction effects (e.g. the effect of income on expenditures differs for whites and blacks). (Again, the problem arises from violation of the assumption that no such differences exist or have already been incorporated into the model.) Richard Williams, Univ. of Notre Dame
  • If heteroskedasticity does not cause bias or inconsistency in he OLS estimators, why did we introduce it as one of the Gauss-Markov assumptions? Hedibert

heteroscedasticiteit


Definition from Stanomics:
Homoscedasticiteit betekent “gelijkheid van varianties” (heteroscedasticiteit betekent dat de varianties niet gelijk zijn).

Example sentence(s):
  • Anders kan een multipele Mann-Whitney-toets, bv. de Bonferroni-toets volgens Holm (26), of wanneer deze gegevens heteroscedasticiteit vertonen maar anderszins consistent zijn met een onderliggende monotone dosis-respons, een andere verdelingsvrije toets (bv. Jonckheere-Terpstra (27) (28) of Shirley (29) (30)) worden toegepast, en deze zal doorgaans de voorkeur hebben boven t-toetsen voor ongelijke varianties. - VERORDENING (EU) 2016/266  
  • Ten slotte wordt getest of er sprake is van homoscedasticiteit. Bij meervoudige regressieanalyse dient de variantie van de residuen constant te zijn, en wel voor elke combinatie van waarden op alle onafhankelijke variabelen. De variantie van de residuen mag dus niet afhangen van de waarden van de onafhankelijke variabelen. Is dit wel het geval dan spreekt men van heteroscedasticiteit. Er wordt hier aan de voorwaarde van homoscedasticiteit voldaan. - Universiteit Gent  
  • Heteroscedasticiteit heeft echter wel een grote invloed op de standaard error en daarmee dus ook op de betrouwbaarheidsintervallen en de significantietoetsen van je parameters. - WikiUvA
