ErrorComponents {ImpuR} | R Documentation |
Crude estimation of noise (as a function of wavelength) and heteroscedasticity of a spectime object. Uses singular value decomposition to approximate the signal.
ErrorComponents(object, err.win = 1:10, nerr = 3, nfit = 5, df = 10)
object |
a spectime object |
err.win |
the times (rows) to use to estimate the noise |
nerr |
the number of svd components to estimate the noise |
nfit |
the number of svd components to estimate the heteroscedasticity |
df |
degrees of freedom for smoothing of noise function |
a spectime object in which the slots @std.err and @hetero are filled in
Somewhat crude.
