PchX(Input: ITimeSeries, Lag: Integer)
Input. Variable
Lag. The parameter sets a shift (lag) of variable points in a time period. It can take only positive values. Optional parameter. By default the parameter is 1 - previous period.
It calculates the rate of change of variable points to the specified period.
| Formula | Result | Application |
| = PchX({Brazil|BCA},3) | The rate of change of Brazil|BCA factor observations is calculated to the period shifted from current by three points. |
It can be used in formulas of calculated series of time series database and model formulas of modeling container that is a child of the time series database. |
| = PchX(X1,2) | The rate of change of X1 factor points is calculated to the previous period shifted from current by two points. |
It can be used in model formulas of modeling container. |
