We can now define positive and negative predictive value as follows: Positive predictive value = a / (a+b). Negative predictive value = d / (c+d). Post-test probability of disease given a positive test = a / (a+b). Post-test probability of disease given a negative test = c / (c+d). Notice that we are now using the rows instead of columns, as for sensitivity and specificity.
Knowing the covariance of stocks helps you build a better portfolio. The covariance of two variables tells you how likely they are to increase or decrease simultaneously. A high, positive covariance between two stocks means that when the price of one goes up, that of the other usually does too.A high negative figure means that when one stock advances, the other generally retreats.inding the Covariance. Now you will have two sets of data: the daily deviation of Stock A from the average price of Stock A; and the daily variation of Stock B from its average price. For each day in your data set, multiply the deviation of Stock A by the deviation of Stock B.
