Hi, could I see a copy ?
Thanks, Mario

Dr. Thank you for your response.
However, my question is not in regards to applying Six Sigma practices but rather general info on the industry.
My situation is I suspect that the financial reporting processes and resulting DPMO in my company is above the industry norm. I just want to benchmark my company against average expected values. On…[Read more]

I appreciate you responding to my email. My question was regarding information regarding the industry. e.g. Financial data inputting can be expected to have 1000 DPMO’s.
Do you know of any source where I can find average defect rates for financial operations like data input, general ledger, etc?
Thanks again.

thank you for your answer but i am still confused. if i look at 2.3 on the z table, i get .04893. i feel i am looking at wrong table? i search this site and found one that looks just like mine with same answer.

Mario replied to the topic negative contingency matrix entries for chi square? in the forum General 17 years, 10 months ago
Actually adding a constant to every cell fixes the problems of expected frequencies less than 1, and 20% expected frequencies less than 5. The problem however is that depending on which constant you add to every cell, the chisquare value is different…

Mario replied to the topic negative contingency matrix entries for chi square? in the forum General 17 years, 10 months ago
Yes, I think that is better. In that case my range of real values is shifted from [1,1] to [0,2], so there are no negative values in the matrix, but the distances between the matrix values are preserved. I might still get 0 for Ei because the matrix might be all 0’s. So mabye I should add 2 to every cell and get the [1,3] range i…[Read more]

Consider for example the following 4×4 matrix where the values are reals from the range [1,1]:
0 .5 .3 .3
1 1 1 0
0 1 1 1
1 0 0 0
I would like to know if the rows and columns are independent, and more generally if the distribution of these values is from a particular expected distribution. There are no populations and frequencies here,…[Read more]

Maybe then I am applying chi sqaure to the wrong problem? I have a matrix populated with values in [1,1]. I want to find out if the rows and columns are stochastically independent.

How are Ei=0 values handeled in x^2 = (OiE)^2/Ei?

Hi Statman and Tim,
You guys did a great job regarding this question. Let me add a minor suggestion to this discussion.
With your testing approach, you want to prove that the new process has the nonconformance that is just lower than the current one. That may not be enough for PA because he needs to prove that the new process has the n…[Read more]

Hi PA,
The quotes from your posts:
1) I have a process in which historically we have 20 % nonconformance.
2) The present leak rate presently is 30 %.
Some initial questions for you:Is your process getting worse?
How do you define a failure in your test?
Thanks,
Mario
