Value
All tidying methods return a data.frame without rownames, whose
structure depends on the method chosen.tidy returns one row for each coefficient in the model,
with five columns:
term
The term in the nonlinear model being estimated and tested
estimate
The estimated coefficient
std.error
The standard error from the linear model
If conf.int = TRUE, also returns
conf.low
low end of confidence interval
conf.high
high end of confidence interval
glance returns one row with the columns
sigma
the square root of the estimated residual variance
logLik
the data's log-likelihood under the model
AIC
the Akaike Information Criterion
BIC
the Bayesian Information Criterion
Details
augment is not currently implemented, as it is not clear
whether ARIMA predictions can or should be merged with the original
data frame.
