Syntax: MASS numberor MASS keyword=number [ keyword=number [ keyword=number]]
where number is 1,2,4,6,8,10,12,14,16,20,24,28,32,36,40,44,48,56,64,72,
80,88,96,104,112,128,144,160,176,192,208,224,240 or 256
and keyword is FIRST, SECOND or THIRD.
MASS FIRST=
MASS SECOND=
MASS THIRD= The default number of quadrature points used is 12.
A large number of mass points will produce more accurate integration, but will increase the time taken for each iteration.
For binary data, using a mass point of 1 with end-points free is equivalent to
ignoring the case-structure of the data, and fits the famous mover-stayer
model of Blumen Using a mass point of 1 with end-points fixed at zero is equivalent to a standard logistic/log-linear model (and thus to using the LFIT command). The MASS setting has no effect on the LFIT command. The current setting of the MASS parameter may be obtained by issuing the DISPLAY SETTINGS command. |
