Regression; how to get t-values for all parameters estimates
...e to obtain the corresponding t-values for ALL parameters (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...
