detrend(signal::AbstractVector, order::Int=1; verbose::Bool=true)

Detrend a signal by removing polynomial trend of order p using build in least squares .

Args:

• signal Data Vector containing te signal
• order=1: order of polynomial

Return:

• (detrended_signal, coefs): The detrended signal and the estimated coefficients from order 0 to p

Examples

julia> signal = sin.([1:100;]) + 0.03 .* [1:100;] .+ 1
julia> _, coefficients = detrend(signal)
