Give some examples where a simple correlation coefficient has a sign opposite to that of the corresponding partial correlation coefficient and comment on it.

The sign of partial correlation coefficient is the same as the sign of linear regression coefficient. If we assume meeant the three variables are centered their means were brought to 0the what is meant by correlation coefficient of a linear regression coefficient found whatt many textbooks could be written as follows:. If we substitute all SCP in the numerator accordingly and then simplify we'll get that the numerator is proportional to the quantity. I take it you want to know intuitively why the partial and simple autocorrelations could have opposite signs.

Consider the following fictional scenario. In a given town, people get fatter as they get older. As a consequence, their doctors recommend that they exercise more. So older and fatter people exercise more than young, skinny ones. The correlation between weight and exercise would be positive simple correlation.

But if you adjust for age, you would find that those who exercise have lower weight than those that do not exercise for a given age. Sign up to join this what is meant by correlation coefficient. The best answers are voted up database design diagram examples rise to the top.
