Margins saving error

[Alistair Grant]

Hi Statalist,

I'm having trouble saving a margins dataset after running a non-parametric regression and I'm struggling to see where my mistake is.

After opening my dataset, my exact code is:

npregress kernel std_dev n if c5==1 & year==2018, vce(bootstrap, reps(100) seed(100))
margins, at(n=(1(1)32)), saving (marginsus)

Stata returns with:

invalid 'saving'
r(198);

How can I resolve this issue?

Too many commas. Eliminate the comma that precedes -saving(marginsus)- and it will run without complaints. In Stata syntax, a comma is used to separate the start of a command from its options, but it is not used between two options.

Problem solved, thank you.
