Look at your R-squared: it is equal to one. You have a perfect fit.

Subject: <SPAM>st: No Std. Err, t, P>|t| or Conf. Interval in Regression
Result
Hello,
I am trying to run regressions with my data but somehow it does give me
the coefficient but no result for Std. Err, t, P>|t| or Conf.
Interval.
See example below where:
delta_sic6 = between 0 and 1 (it's a percentage) delta age,
delta_quality and delta_rba are hedonic characteristics (values between
-100 and 100) which are multiplied by dummy variables
id_*
What am I doing wrong that is causing this problem and how do I solve
it?
Thank you in advance.
Bianca
