81028 I’ve been making progress again on the Deep Learning Nanodegree and should be completing the second project in that course very soon.  On the 6th of November the second term of the Data Analyst Nanodegree opens back up and I will continue working on both of these Nanodegrees while working on some other business projects.

81022 Successfully completed the 4th Project of the Udacity Data Analyst Nanodegree Term 1 yesterday. This project was on the topic of A/B Testing using a 294,478 row, 5 column data set and eventually joined with a second data set. This project develops a better understanding of hypothesis testing using null and alternate hypothesis, confidence intervals, Type I and Type II error rates or Alpha and Beta rates. The project flow was from manual probability calculations to using z_tests and p_value functions from the ‘statsmodels.api’ library then to multi variable logistics regression analysis and determination of statistical significance from the results of all three. The project also involved bootstrapping simulated data using a numpy random binomial generator. Next step is to start Term 2 and continue the Deep Learning Nanodgree Term 1.

81021 Submitted my fourth and final project for the first term in the Udacity Data Analyst Nanodegree that I’ve been working on for several months now.  Hopefully it will pass the requirement.

81006 It’s been a frustrating day concerning the progress on my 3rd project in the Udacity Data Analyst Nanodegree. The problem started this afternoon when the jupyter notebook I have been working in for about a month crashed. In other words I am getting the error message that the kernel died and although it tries to restart that’s not happening.

I’ve submitted an issue with the jupyter help on GitHub after researching the issue online and not finding the correct answer. Hopefully somebody will be contacting me soon on how to resolve the issue.

This all happened right after I updated the Seaborn application but I am not sure if that had anything to do with it or not it might have also been caused by the Apple Xcode application that I’ve had conflicts with many times before. Who knows?

Update 3 hrs later. After removing the Anaconda application and seaborn application and reinstalling the Anaconda application the kernel is now working again. I’ve submitted the 3rd project for the second time and passed the requirements and moving on to the forth and last project in term one now.

Update 12 hours later: The project submission received a successful review since my last update and I’ve resumed working on the fourth and final project A/B testing which will complete this Nanodegree. Two out of three down and one to go.
