Residuals of a trend filtering model

Get residuals from a 'trendfilter' object.

# S3 method for trendfilter
residuals(obj, lambda = NULL, x_eval = NULL, zero_tol = NULL, ...)

Arguments

obj	Object of class trendfilter.
lambda	One or more lambda values to compute residuals for. Defaults to lambda = NULL, in which case, residuals are computed for all hyperparameter values in obj$lambda.
x_eval	Vector of inputs where the trend filtering model(s) will be evaluated. Defaults to x_eval = NULL, in which case x_eval = obj$x.
zero_tol	Threshold parameter that controls the point at which a small coefficient value is set to zero. Defaults to zero_tol = 1e-10.
...	Additional named arguments. Currently unused.
