WebThe calculation is simple. The first step consist of computing the linear regression coefficients, which are used in the following way to compute the predicted values: \hat y = \hat \beta_0 + \hat \beta_1 x y^ = β^0 +β^1x. Once the predicted values \hat y y^ are calculated, we can compute the residuals as follows: \text {Residual} = y - \hat ... WebWe can test for such normality (and hence test for a null-effect experiment) by using the normal probability plot. Normal probability plots are easy to interpret. In simplest terms: if linear, then normal If the normal probability …
