    Interpretation of log transformed first differences in SVAR models

    I am working with a structural VAR analysis, and want to understand my results. The model studies how a shock on one variable affects a second variable. I understand that if the first month's response is +3 %, it means that the initial value of the response variable increases by 3 percent...

    Interpretation interaction term in glmer()

    Hi, I am using the glmer() function from the package lme4 for a mixed logistic regression model. Here, the formula is Y ~ X + Z + X:Z, where Y is the binomial outcome, X is a categorical predictor with 3 levels (X1, X2, X3, where X1 is the baseline), and Z is a continuous predictor. In the...

    Physical interpretation of an AR(n) series

    Hi, I am learning TS analysis but my angle is probably diffent from the usual. Being in six sigma I need to reduce the variability of a process that I can prove is basically AR(3) which with 3 runs on the average per day means one day's runs influence the next day in the mathematical model...

    Interpretation of an AR model

    hi, looking at process times of a rather complex machine I found that an AR(2) model describes it quite well. Does it make sense to interpret this as an indication that the machine has a "memory" of about 2 runs ? E.g. insufficient cleaning between runs? thanks a lot!
