I am attempting a simple task of identifying structural breaks in a single
time series trend.
There is a single dep var t=1994-2021, two variables in X viz. constant and
time
The following error message comes up
The variable X is read-only
*** error in function SB_GUI, line 7
list X = !nelem(X) ? null : X
Some guidance would be welcome
.
