Multiple Linear Regression Analysis
THE DATA SPECIFICATION
The data specification consists of an unstructured series of numbers
(the data statement), preceeded by the keyword "Data" and terminated at the
next keyword. The structure is imposed onto it by the input formula.
A sequence of symbols is considered a number when it satisfies the
definition of number in the formal definition of a user program, together
with the machine dependent restrictions imposed by the underlying SIMULA
programming system. Note that the definition of number does not allow
FORTRAN-like numbers as for instance 10. or 1# (at least one digit must
follow). It is recommended to use blanks as delimiters between numbers,
but the use of other non-numerical symbols as delimiters will not lead to
fatal errors, only to a slight increase in processing time.
If a datafile is specified in response to the datastream request or is
appended to the "Run" keyword, the program will try to read a record of
input data, which then do not have to be preceeded by the keyword "Data",
from that file. The record ends at the next "Eor" keyword. However, a non
empty data specification in the user program will get priority over reading
input data from the specified file, while an empty data specification
causes the program to start reading the next record of input data from the
specified file. If the data specification as well as the next nonempty
record in the data file does not contain any numerical information, an
error message is supplied.
