| INDEX
To calculate Indexes it is necessary to have prices
and quantities for at least two commodities.
In general, the format is:
INDEX p1 q1 p2 q2 p3 q3 ... pn qn / options
The available options are:
| Option |
Description |
|
ALTERN
|
Normally, the variable list is as described above, where p and q alternate in the list.
|
|
CHAIN
|
Chains the Laspeyres, Paasche or Fisher indices using the method described above. The Divisia index is always chained.
|
|
EXPEND
|
Indicates that the quantity variables measure expenditures rather than quantities.
|
|
NOALTERN
|
Lists all the prices then all the quantities.
|
|
NOLIST
|
The price and quantity indexes are not printed.
|
|
BASE=
|
Specifies the observation request for a base year to use for the index.
|
|
DIVISIA=
|
Specify the type of index to be calculated and
the variable into which the result should be placed.
If a quantity index is desired, the option name
should begin with a Q. Option names not beginning
with a Q refer to price indexes.

FISHER=

QDIVISIA=

|
QPAASCHE=

|
QLASPEYRES=

|
QFISHER=
|
If there is a zero price or quantity in any year the commodity will
be ignored for that year. To compute a quantity indexes reverse the p and q variables on the
INDEX command.
