If you are open to using R and if the abrupt change around x = 10^-2 can be regarded as a change point from a slope to a plateau, then consider using the R package mcp after log-transforming both your predictor and the outcome. Specifically: fit = mcp (list (y ~ 1 + x, ~ 0), data = df). – Jonas Lindeløv.

Webpxx = pcov(x,order) returns the power spectral density (PSD) estimate, pxx, of a discrete-time signal, x, found using the covariance method.When x is a vector, it is treated as a single channel. When x is a matrix, the PSD is computed independently for each column and stored in the corresponding column of pxx.pxx is the distribution of power per unit frequency.
