Ginga Specific Software: Program REGRESSION
Program regression performs a weighted or unweighted linear
regression between two Ginga housekeeping (HK) parameters.
A Ginga CUBE or TIME series containing HK parameters.
However, the program will also work with any HDS file containing two
one-dimensional arrays of equal size, providing it also contains an
array NELS(3) (where NELS(1) is equal to the size of the
one-dimensional arrays).
Regression requires five input parameters. The QX parameter
system is used to read these parameters.
| REG_DATIN | The name of the input CUBE
or TIME series. |
|
| | REG_YNAM1 | The name of the array
containing the dependant variable. |
|
| | REG_XNAM1 | The name of the array
containing the other variable. |
|
| | REG_YERR1 | The name of the array
containing the error on Y. If NONE then only unweighted
regression occurs. |
|
| | REG_IGNORE | If any of the data values
in X or Y equal IGNORE then this point is omitted from the
regression. |
