WebUnfortunately, simple X-Y plots may not be as useful in multiple regression as they are for simple linear regression. If there is multicollinearity, then that can cause the plots of Y against individual X values to be misleading. For example, the apparent increase in variance for Y as X1 increases might be due to the effect of other X variables ... Web7 de ago. de 2024 · Assumption 4: Residual errors should be homoscedastic. In the previous section we saw why the residual errors should be N(0, σ²) distributed, i.e. normally distributed with mean zero and variance σ².In this section we impose an additional constraint on them: the variance σ² should be constant.Particularly, σ² should …
