Variable ROWTYPE_ (MATRIX DATA command)

  • ROWTYPE_ is a string variable with A8 format. Its values define the data types. All matrix data files contain a ROWTYPE_ variable.
  • If ROWTYPE_ is specified on VARIABLES and its values are entered in the data, MATRIX DATA is primarily used to define the names and order of the variables in the raw data file.
  • ROWTYPE_ must precede the continuous variables.
  • Valid values for ROWTYPE_ are CORR, COV, MAT, MSE, DFE, MEAN, STDDEV (or SD), N_VECTOR (or N), N_SCALAR, N_MATRIX, COUNT, or PROX. For definitions of these values. See the topic CONTENTS Subcommand (MATRIX DATA command) for more information. Three-character abbreviations for these values are permitted. These values can also be enclosed in quotation marks or apostrophes.
  • If ROWTYPE_ is not specified on VARIABLES, CONTENTS must be used to define the order in which the records occur within the file. MATRIX DATA follows these specifications strictly and generates a ROWTYPE_ variable according to the CONTENTS specifications. A data-entry error, especially skipping a record, can cause the procedure to assign the wrong values to the wrong records.

Example

* ROWTYPE_ is specified on VARIABLES.
 
MATRIX DATA
     VARIABLES=ROWTYPE_ SAVINGS POP15 POP75 INCOME GROWTH.

END DATA.
  • ROWTYPE_ is specified on VARIABLES. ROWTYPE_ values in the data identify each record type.
  • Note that VARNAME_ is not specified on VARIABLES, and its values are not entered in the data.

  • CONTENTS is required to define the record types and the order of the records in the file.
