Dear All,

I am working on psmatch2 command where I am trying to use various matching methods including "spline" method using the following command.

"psmatch2 depvar indepvars , spline outcome(variable)"

After running this command, I am getting warning message like "You need to install package -spline-, for option spline /// r(198);"

However, I have tried installing "spline" using help command and from this link "st0547 from https://ift.tt/3h8UyZ2". The installation also is done succesfully. But still the psmatch2 command gives me a same message again. Can any one say me what is the problem that I am facing? and I would be greatfull to you if any one could solve this problem?
