The DATA sub-menu
The DATA sub-menu contains functions used to manipulate the statistics matrix
The operation of these functions is as follows:
+ : add row in level 1 to bottom of DATA matrix.
- : removes last row in DATA matrix and places it in level of 1 of the stack.
The modified DATA matrix remains in memory.
CL : erases current DATA matrix.
DAT: places contents of current DATA matrix in level 1 of the stack.
„ DAT: stores matrix in level 1 of stack into DATA matrix.
The PAR sub-menu
The PAR sub-menu contains functions used to modify statistical parameters.
The parameters shown correspond to the last example of data fitting.
The parameters shown in the display are:
Xcol: indicates column of DATA representing x (Default: 1)
Ycol: indicates column of DATA representing y (Default: 2)
Intercept: shows intercept of most recent data fitting (Default: 0)
Slope: shows slope of most recent data fitting (Default: 0)
Model: shows current data fit model (Default: LINFIT)
The functions listed in the soft menu keys operate as follows:
XCOL: entered as n @XCOL, changes Xcol to n.
YCOL: entered as n @YCOL, changes Ycol to n.
