We can now test this hypothesis by calculating the correlation and plotting a scatterplot of these two variables. In addition, we can also do a linear regression and see how it performs: cor(cars_data$wt, cars_data$mpg) install.packages("ggplot2") require(ggplot2) ggplot(cars_data, aes...
statistical analysis, and process improvement tools. Minitab makes it simpler than ever to get deep insights from data. It involves elements like Scatterplot, Boxplot, and histograms, which collectively can help six sigma professionals

This is the final scatterplot of the data under the assumption of normal marginals and t-copula for the dependence structure: As you can see, the t-copula leads to results close to the real observations, although there are fewer extreme returns than in the real data and we missed some of...
2.5.1 Adding a smoother to a plot If you have a scatterplot with many data points, it can be hard to see exactly what trend is shown by the data. In this case you may want to add a smoothed line to the plot. This is easily done using thesmoothgeom. ...
