CUSUMS:

Due to daily plant variations, time series do not often show the time at which a change has occurred.
Instead, cumulative sums are used to identify the time of changes in operating parameters.

To use:

Enter the dates, parameters' names and their values for each day.

The parameters'values for the first day (first row) must not be empty.
The other rows can be empty if no data are available on particular days.

Click on "Calculate" to calculate the cumulative sums and plot graphs.
