WebRecall that the regression equation (for simple linear regression) is: y i = b 0 + b 1 x i + ϵ i. Additionally, we make the assumption that. ϵ i ∼ N ( 0, σ 2) which says that the residuals are normally distributed with a mean centered around zero. Let’s take a look a what a residual and predicted value are visually: WebThe Normal Probability Plot. A normal probability plot is a graph that plots the observed data versus the normal score, which is what we would expect if the data actually …

Webe. From StatCrunch output graphs, provide the histogram and the normal probability plot (QQ plot) of the residuals of your regression model. Does this regression appear to meet the condition of near normality? Also, using StatCrunch output data, create a scatterplot of studentized residuals vs predicted values and comment on the equal variance assumption. http://www-stat.wharton.upenn.edu/~stine/shiny/quantile_plot.pdf philippe briard boulanger a caen et fils
