    Both binary and I had a nominal.  I just didn’t want to get too much in the details on a discussion board – it was a 2 year project and can’t really be discussed well like this (too much detail, you know).  Don’t want to get in semantics on test versus data analysis.  I’m just a simple BB who wants to share with the original poster that there are…[Read more]

    Regarding the comments why logistic regression – quite simple – we were measuring the days to birth outcome:  one discrete, one continuous (I won’t get into details other than that on a discussion board, if you don’t mind).  Rest assured – I ran the correct test for the data.  If regression would have worked I would have used that test – it’s eas…[Read more]

    I’ve just completed an ALOS project to reducing NICU stays.  It was a challenging project to complete due to the many variables stated in this thread, but it’s a very viable and measurable stat for any medical operation (hospital or insurance).  Be prepared to become very familiar with Logistic Regression tests.  Needless-to-say I wouldn’t shy aw…[Read more]

    I have completed a signficiant ALOS project with substantial reductions and cost avoidance.  I’m not sure what ALOS you’re looking to reduction, but would be happy to BP share.  Do you have an email or phone#?

    Well said, Brandon.  And thank you for your response (and the heads up).  I’ve been a reader on these boards for a year, but have only engaged in discussions recently.
    Regards.

    I’m not sure what you’re driving at, to be honest, NYSE.  I don’t know anything about the 4 people you listed except with an assumption we are all data-driven people who use methodologies like Six Sigma to improve.  I doubt, highly, they are the reasons behind any impact on stock price for any company.  I could be wrong – who knows. 
    If we are…[Read more]

    I didn’t read that.  I didn’t see anything that indicated what kind of data he was working with.

    You are wrong and it’s sad that you don’t know that.  Margin is great.  Growth is what companies need.  Quality & Process Improvements continue.  Biopharma is continue to grow in the industry and they are more than in the landscape. 
    Either you don’t like GE or you hear people who don’t like them.  Read the stock reports and you’ll see a diffe…[Read more]

    This isn’t making more out of the question.  Running a normality test is part of it, but also running a test of equal variance may also be needed.  At the end of the day, if you run the wrong test you P value will hold no value.  You will either have an Alpha or Beta error.  It all depends on the data. 
    I just don’t want to send you off in the…[Read more]

    I am a former GEMS/GEHC employee.  If you have not worked there I assure you are unlikely unable to determine the true successes Six Sigma and Lean have on that company. 
    GE has managed to save billions of dollars in poor quality and create new product lines that have saved 1000’s of lives.  Six Sigma and Lean still live and breathe in GE.  It…[Read more]

  • not a doc replied to the topic Accepted P Value in the forum General 15 years ago

    Hi.  This statement isn’t 100% accurate:   the p-value > 0.05 we fail to reject the null hypothesis and accept that the data is normal.  You can have non-normal data in any non-parametric test.  Just because the P is >.05 won’t make the data normal. 
    You have to run a normality test before you run the correct statistical test.  If you don’t…[Read more]
