Re: st: probing interactions with continuous variables with mi test / mi test transform

[daniel klein <klein.daniel.81@googlemail.com>]

Without going into the statistical issues, please read the error
messages and try to make sense out of them, which is usually not too
hard. If Stata tells you, it cannot find a variable "mi" you should
check why Stata is interpreting any "mi" in your syntax as a variable.
I guess it is because you used too many "////". Your code says:

[...] trustmleC knowlmleC knowlmleCXbsent3ae ///
mi test sdb avg sda ///

Since the command (mi estimate : regress) does not end after the first
line, Stata searches for the next variable in the secound line, which
is "mi" and which does not exist. In Stata "///" means: the command is
not yet finished. So you should get rid of "///" in _both_ lines.

In your last example your open brace is "[", where Stata expects "("
as used in Sytaxes above. Stata looks for the mi subcommand "[diff1",
does not find it, and tells you about it.

Best
Daniel
