# Homoskedastic error term in regression

Homoskedastic (also spelled "homoscedastic") refers to a condition in which the variance of the residual, or error term, in a regression model is constant. Homoskedasticity is one assumption of linear regression modeling. Heteroskedasticity refers to a condition in which the. An error term is defined as a variable in a statistical model, which is created For example, assume there is a multiple linear regression function that takes Heteroskedastic refers to a condition in which the variance of the. Homoskedasticity. How big This means that the variance of the error term u is the same, . The multiple regression model describes the relation between the. Homoscedasticity describes a situation in which the error term (that is, the “noise” or random disturbance in the relationship between the independent variables. The error term is the most important component of the classical linear regression model (CLRM). Most of the CLRM assumptions that allow econometricians to. The error term of our regression model is homoskedastic if the variance of the some bivariate heteroskedastic data, estimate a linear regression model and. In statistics, a sequence or a vector of random variables is homoscedastic deviations of the error terms are constant and do not depend on the x-value. Start studying Chapter 5 Econometrics. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Homoskedastic refers to a condition in which the variance of the error term in a regression model is constant. The multiple log-linear model • The coeﬃcient βk is the elasticity of the response variable Y with respect to the variable Xk, i.e. the expected relative change of Y, if the predictor variable Xk is increased by 1% and all other predictor variables remain the same (ceteris paribus). • If Xk is increased by p%, then (ceteris paribus) the expected relative change of Y is equal to βkp%.
