Skedasticity refers to the distribution of residual variance in regression analysis, which varies across the levels of a particular independent variable or across different subsets of the data. In simpler terms, it's a statistical concept that deals with the variability in the spread of residuals around the regression line, and how that variability changes under different conditions or subgroups of the data.<br><br>More formally, it's often used to describe the idea that the homoscedasticity (consistent variance) assumption of linear regression models is not met, meaning that the variance of the residuals changes systematically with the level of the independent variable. This can lead to biased or inefficient estimates of the regression coefficients, among other problems.
A skein is a rope, string, or yarn that has been twisted or wound together, typically to make it easier to handle or manage.
