For example, moving μ from 0 to 1 will reposition the entire distribution over to the right by one unit. The variance and its square root, the standard deviation, are scale parameters determining how wide the distribution will be. For example, if the standard deviation is tripled, it will widen out the distribution by a factor of 3. The skewness and kurtosis are shape parameters. The skewness tells us the amount of symmetry. When zero, there is perfect symmetry. When negative, there is left-skewness, where the tail on the left is elongated.
Lists can contain lists. We can see the difference in the code output sequence below. 7 Lists 21 > #Lists: > c(1,c(1,2),3,"A",c(4,5))  "1" "1" "2" "3" "A" "4" "5" > list(1,c(1,2),3,"A",list(4,5)) []  1 []  1 2 []  3 []  "A" [] [][]  4 [][]  5 If l is assigned to our list above, referencing elements can be done in two ways. l yields a list of the vector c(1, 2), whereas l[] yields just the vector c(1, 2) itself. > l <- list(1,c(1,2),3,"A",list(4,5)) > l []  1 2 > l[]  1 2 We can see that our data frame, e, from earlier can be treated as a list in the following sequence.
So, the question may arise: why was the Greece problem such a big deal? It was because of the structure of EU bailout funds and the composition of European bank balance sheets: • Spanish and Italian banks were heavily exposed to Greek debt. • If Greece goes bust then part of the bailout must be paid by Spain and Italy. • Another problem is that Italian and especially Spanish debt is too high for those countries to pay their share of the Greece bailout and bail out their own banks. • So the danger was that a Greek collapse would lead to a chain of events that would force most of southern Europe to break away from the Euro.
