Regression; how to get t-values for all parameters estimates
...not just the
number of effects minus 1, provided by summary()). Does anyone know how to get
(all of) them?
Here comes what I've already tried:
## Try data:
> Data <- rbinom(1000,50,.9);
> Dates <- Sys.Date()-(1000:1)
> facweek <- factor(weekdays(Dates,abbreviate=TRUE))
> facmonth <- factor(months(Dates,abbreviate=TRUE))
> contrasts(facweek) <- contr.sum ;
> contrasts(facmonth) <- contr.sum ;
> fit <- lm(formula = Data ~ facweek + facmonth)
> summary(fit)
Call:
lm(formula = Data ~ facweek + facmonth)
Residuals:
