WebIn stochastic processes, chaos theory and time series analysis, detrended fluctuation analysis ( DFA) is a method for determining the statistical self-affinity of a signal. It is useful for analysing time series that appear to be long-memory processes (diverging correlation time, e.g. power-law decaying autocorrelation function) or 1/f noise .

WebNov 26, 2024 · Step 1: Make an initial state “A”. The minimum possible string is 01 which is acceptable. For this, make the transition of 0 from state “A” to state “B” and then make the transition of 1 from state “B” to state “C” and notice this state “C” as the final state. Step 2: Now, we have designed the DFA that start with 01.
