Davis M. Course Outline. This 3 hour course presents a review and overview of practical and simple statistical methods that can be used for process improvement. Practical how-to information for gathering data and converting it into useful information for process improvement is presented. This course will also provide help organizations that are either ISO , , , TS or AS registered or seeking registration to meet the requirements for process and product monitoring and measurement as well as data analysis and continual improvement found in the standards.

This course includes a multiple choice quiz at the end, which is designed to enhance the understanding of the course materials. Learning Objective. Intended Audience. Engineers, consultants and managers interested in understanding process or product monitoring and measurement as a part of the CI process and to more effectively manage your business using facts will benefit from this course. Benefit to Attendees. Course participants will learn how to use simple, powerful and practical statistical methods for process improvement that can guide fact based decision making.

Course Introduction. To prosper in today's economic climate, companies and their suppliers must be dedicated to never-ending improvement in quality and productivity.

Tutorial: Statistics and Data Analysis

Most everyone agrees that "Doing it right the first time" and the policy of prevention are sensible and even obvious philosophies which will, when adopted, improve the quality of all the products manufactured or services provided by any company. Quantitative measures are needed to effectively monitor process and product or service performance. Statistical methods can provide the data and information to more effectively manage your business. The underlying principles are found in the basic concepts of statistics and Statistical Process Control or SPC and its associated problem solving techniques.

To much statistics knowledge is also not good for creating machine learning model. Sometimes a statician ignore a feature because he thinks it does not much affect the dependent variable. But in fact in prediction, combination of features can create very good prediction power.

We solve this sometimes by involving multiple divisions in this process. These people have a different perspective on the problem to be solved. Statistical methods provide the basis, complement and verify. Then take a look at the differences and it will get interesting.

A confidence interval is used in the presentation of model skill. Hypothesis test is used to confirm that the differences between models is real. Great summary of usage of stats in machine learning. Particularly usage of inferential statistics in ML.

In order to make a ML model that can predict the labels ,is it compulsory to use these statistical methods? Hello, it may not be the right publication to make this query, I apologize in advance. Well, it turns out that I have a database that I intend to analyze in order to obtain some prediction.

But it turns out that these data are not numerical so to speak but words. I will give you a small context, it turns out that the data I have are telecommunications equipment alarms, these alarms are categorized by a priority level, in addition there are other types of parameters that show characteristics of the equipment in question. How would you deal with this case? I had thought about binarize my data, leaving only with level 1 what I want to predict and level 0 for others, but I think it would lose intrinsic characteristics of the system, Is there any method that allows the treatment of these situations?

I would recommend encoding the words or text. An integer encoding, bag of words or one hot encoding might be a good place to start. More advanced encoding may follow. Name required.
