The result is comparable to that of SAS PROC REG.
The first part is ANOVA table.
The second part is measures about fitness.
The third part is the estimates of coefficients.
- Estimate
point estimate of parameters, coefficients
- Estimable
estimability: 1=TRUE, 0=FALSE. This appears only when at least one inestimability occurs.
- Std. Error
standard error of the point estimate
- Lower CL
lower confidence limit with conf.level
- Upper CL
lower confidence limit with conf.level
- Df
degree of freedom
- t value
value for t distribution
- Pr(>|t|)
probability of larger than absolute t value from t distribution with residual's degree of freedom
The above result is repeated using HC0 and HC3, with following White's first and second moment specification test, if HC option is specified.
The t values and their p values with HC1 and HC2 are between those of HC0 and H3.
- Fitted
Fitted value or y hat. This is returned only with Resid=TRUE option.
- Residual
Weighted residuals. This is returned only with Resid=TRUE option.
If summarize=FALSE
, REG
returns;
- coeffcients
beta coefficients
- g2
g2 inverse
- rank
rank of the model matrix
- DFr
degree of freedom for the residual
- SSE
sum of square error
