For instance, to build an index on Brazil’s GDP, base year 2010:
- search for Brazil’s GDP
- copy the 2010 value
- change to the calculator menu
- find the formula generator, the one which shows Brazil’s GDP identifier already…
- divide it by the base year as stored in your clipboard (don’t forget to add the “/” first)
- and finally, multiply the formula by 100 to build the index number…
For any single time series some general statistical figures are calculated automatically:
- the minimum and maximum value
- the mean
- the standard deviation
- the co-variance
Ref. the above example: simply click to the corresponding icon beside the new calculated “Brazil GDP index number” series.
The calculator also provides a powerful transformation tool which comes with a number of predefined hard wired functions:
- lag
- moving average
- interpolation of missing values
- forecast
and formulas:
- for calculating the difference per time series selected (t-(t-1)) and
- the rate of change (t/t-1): compounded or continuously compounded
