optimal_span | R Documentation |
The optimal span is calculated based upon the bayesian information criterion (BIC).
optimal_span(
y,
x = NULL,
weights = NULL,
step = 0.01,
label = NULL,
plot = FALSE
)
y |
a vector with measurement values to smooth |
x |
a vector with dates / time steps |
weights |
optional values to weigh the loess fit with |
step |
span increment size |
label |
title to be used when plotting function output |
plot |
plot visual output of the optimization routine |
Returns an optimal span to smooth a provided vector using the 'loess()' smoother.
