Matlab Project1

Deadline - 18 Hours

Most of the project has been completed. I just need the finishing touch.

Instructions:

This is a data analysis. I finished most of them, but some of them I cannot find out how to do that.

1, I have to get a low pass filterplot

2, I have get a signal subject boxplot

1,Choose a threshold for both the maximum and minimum acceleration to differentiate between the Falls and Non-falls. How many activities are falsely identified as falls with these thresholds (false positives)? How many falls are not correctly identified with these threshold (false negatives)? How do your threshold values compare to those in the paper?

2, Choose one subject and plot the single-sided spectrum for each activity. What differences do you notice?

3, Apply a low pass filter to the data and repeat problem 2 ?

Question to finish

1, Choose a threshold for both the maximum and minimum acceleration to differentiate between the Falls and Non-falls. How many activities are falsely identified as falls with these thresholds (false positives)? How many falls are not correctly identified with these threshold (false negatives)?

2, What is a better quantity to consider for detecting falls, maximum acceleration magnitude or minimum acceleration magnitude?

3, Choose one subject and plot the single-sided spectrum for each activity.

4, Apply a low pass filter to the data and repeat problem 1.
