  • @jnoguera Doesn’t look simple, but there’s no time like the present to learn something new. Thank you for your help, will report back with my success hopefully sooner rather than later. 3 years, 9 months ago

  • @jnoguera How does exponential smoothing treat seasonality when there are different time intervals to the seasonality. It seems that I have to designate a seasonality cycle for the model to work over time, however, since my cycle is not always the same amount of business days

    What I mean by this is that my “seasonality” is really just a big…[Read more]

  • I think we’re getting a little side tracked here.

    At this point I understand the main difference between Cpk and Ppk, but I still don’t understand why Minitab doesn’t calc Cpk for certain transforms and for distributions.

    I also still don’t understand the difference between Cpk and Ppk when your sub-group size is 1 (or individuals, as @jnogue…[Read more]

  • @Mike-Carnell Yes, a transform or distribution should only be used if it fits the data better, which you can tell using “Individual Distribution Identification”. If the data is not normal, then the resulting Cpk on a normal graph, can be just as misleading as if you transformed data that shouldn’t be. It’s not about maximizing Cpk, it’s about…[Read more]

  • @jnoguera Thanks John. Was hoping for an existing template with a few more capabilities to use a variety of models and then some predicted forecasts. 8 years, 8 months ago
