For a monthly data, the link relative for any month is given by:
Current month's Value / Previous month's value × 100
The correct formula for calculating the link relative is:
Link relative = (Current month's Value / Previous month's value) × 100.
This is used to compare the performance of the current month relative to the previous month, expressed as a percentage.
Let X be a real-valued random variable with E[X] and E[X2] denoting the mean values of X and X2, respectively. The relation which always holds is
Two continuous random variables X and Y are related as
Y = 2X + 3
Let \(\sigma_X^2\) and \(\sigma_Y^2\) denote the variances of X and Y, respectively. The variances are related as
