st: Why Do I get Different Results in Stata and Spss?

[Yuval Arbel <yuval.arbel@gmail.com>]

Dear Statalisters,

I ran the following model in stata and spss and got different results.
Obviously, there are degrees-of-freedom problem in this dataset, but I
wonder whether this is the reason I got very different results.

Here is the output:

. reg close_avg_after1 close_avg_before tal100_before equity_return
leverage inventory_cycle costumers_cycle suppliers_cycle gor
> ss_profit_per liquidity working_capital cash_flowoversales rate_ofnetprofit valuestock equityvsbalance equitymultiplier ratioo
> fshorttermloanslongterm interestcoverageratio rateofsalesexpenses
