    Introductory Time Series

    Thanks noetsi. I did not feel they were appropriate for my application based on a cursory examination in the begininngin but I figured it was worth at least seeking some input from people who may use them on a regular basis. Thanks for your time and your recommendation to consult with Miner...

    Introductory Time Series

    Interesting. It appears I have some research / experimentation to do. Thank you again for your continued replies, insight and time. Tremendously appreciated !!

    Introductory Time Series

    I made a cursory review of control charts ( never heard of them, learned something new today : - ) ) and moving averages. Based on the changes in the bar graph between the three voltage readings, I'd have to make an approx 50 period moving average. Wouldn't that cause an enormous lag ( a 50...

    Introductory Time Series

    I understand exactly what you're saying. The issue though isn't necessarily the "limit". It is the representation of the "limit" throughout time. Again, the IQR confidence band changes radically with time like the bar graph example. As I sit and look at this problem, I am beginning to think that...

    Introductory Time Series

    I normally determine and use IQR values to create sort of a "confidence band" around these voltages. These are based on the time interval and of course the motor voltage output characteristics as each one is different. So, to a degree, yes and no. They act as sort of a "second line of defense"...

    Introductory Time Series

    Thanks for your reply and suggestion noetsi. I have used spectral analysis but it is more useful for static signal analysis. I couldn't find any info on the site or in the FAQ about sending a message to a specific user ( Miner ). Is that possible / recommended ? Scales ( used in Wavelet...

    Introductory Time Series

    Hello Everyone, New member and rather new to statistics / times series problems. I am an electro - mechanical engineer by trade and am tasked with solving with what I believe to be a times series problem. I am looking for some insight as to how I might approach said problem : I have a DAQ (...
