‘the toolbox is installed but i don't know why it still giving that error. ¹

You may have a corrupted path.

Run these from your Command Window or a script:

restoredefaultpath 
rehash toolboxcache

Then try again. (You may have to close and restart MATLAB after this as well.)

If that fails to correct the problem, use the Contact Us link in the top right corner of this page, and request Tech Support. (Run the ver command first, since you will need that output.)

This function is part of the econometrics toolbox, make sure you have the license and have the toolbox installed

>> ver

Check if that function is on path

If you have the toolbox and above command doesn't show the function, try:

>> restoredefaultpath
>> rehash toolboxcache
