Design a detector / classifier using classical techniques to distinguish between healthy and epileptic subjects based on EEG recordings provided in . fif file format.

Design a detector/classifier using classical techniques to distinguish between healthy and epileptic subjects based on EEG recordings provided in .fif file format. The EEG data is recorded using the 10-20 electrode placement system, with each recording lasting 3-5 minutes and sampled at 125 Hz.
Your task includes the following steps:
Preprocess the EEG data: Apply necessary preprocessing steps such as filtering and artifact removal.
Plot the EEG data: Visualize the preprocessed EEG signals.
Feature Extraction: Extract features from the EEG data, including Haar wavelet transform, power spectral density, and Shannon entropy.
Plot PDF: Plot the Probability Density Function (PDF) of the extracted features.
Likelihood Ratio Test: Set up a likelihood ratio test using the extracted features.
Calculate PFA and PD: Determine the Probability of False Alarm (PFA) and Probability of Detection (PD).Plot ROC Curve: Plot the ROC curve showing the relationship between PD and PFA , write a proper matlab code by using diffrent feature.
