And slowness of course. Enjoying a meal with friends or family is the main ingredient of any Italian dish. Italian Sunday lunches are the best example, a unique experience you should try at least once. They say only 5% of Italians eat out on Sundays, while 95% are at home eating as much as humanly possible. Sunday lunch is usually spent at some relativesâ home, in my case my grandparentsâ.
A minus one indicates a perfect negative correlation, while a plus one indicates a perfect positive correlation. A correlation of zero means there is no relationship between the two variables. When there is a negative correlation between two variables, as the value of one variable increases, the value of the other variable decreases, and vise versa. In other words, for a negative correlation, the variables work opposite each other.
If their correlation coefficient approaches +1, and X goes up by one unit, Y will also go up one unit. A correlation coefficient of zero means movement of the X and Y variables is unrelated. Portfolio managers use the correlation coefficient to diversify a portfolio, removing unsystematic risk and reducing volatility. They do this by making sure the securities in the portfolio are as negatively correlated as possible.
