SAMPLE 1 22
READ (USECON.txt) YEAR SAVINGS INCOME
* Estimate the savings-income relationship
OLS SAVINGS INCOME / RSTAT DWPVALUE
DIAGNOS / CHOWONE=11

* Now consider a log-linear relationship
GENR LSAV=LOG(SAVINGS)
GENR LINC=LOG(INCOME)
OLS LSAV LINC / LOGLOG RSTAT DWPVALUE
DIAGNOS / CHOWONE=11

* Estimate models with a lagged dependent variable
GENR SAVL1=LAG(SAVINGS)
GENR LSAVL1=LAG(LSAV)
* Adjust the sample period
