### Re: factor based on deviation from mean

You want the comparison to the mean of the other variables for each observation?

### Re: Copy values from cross-section to entire vector

Can you be a bit more specific about what you are doing? What values in AA need to be copied? Is it the value for one date, or values for a range of dates? Are we matching up observations by-date?

### Re: State Space - Prediction Intervals?

You can request the forecast standard errors and construct intervals from those.

### Re: outliers in a scatterplot

If you are okay with a separate regression line for both the non-2008/2009 values and for the the 2008/2009 values, the easiest way to do this is to create new series that have missing data for subsections of the data. That is, create a series with just the 2008 and 2009 values, and a separate serie...

### Re: Cointegration Test gives wrong P-Value

We've identified the issue. In the MacKinnon algorithm for the response surface, we have found that there are potential issues with the polynomial approximation to the response surface for extreme values. In this case, the statistic value is so out of bounds that the existing algorithm approximation...

### Re: State space restrictions over the values of the state variable

I can't see an easy way to do that since we need linearity in the states.

### Re: Unit Root test with structural break

Sorry, the option was not documented. If you go into the dialog and run it with the additive outlier and look at the command capture, you'll see that the option is "type=ao", as in

Code: Select all

`dyuk.buroot(type=ao)`

Sorry for the inconvenience.

### Re: Ordered Logit Issue

The 99% was a generic comment, not specific to your data (which I haven't seen). What I'd recommend is that you make a model from your equation and solve for the fitted probabilities and examine them. I do note that your 0 category is the least frequent, and though you most certainly have fitted pro...

### Re: Ordered Logit Issue

The model is what it is. If you have a better model, then you can use it instead. Adding explanatory variables may help, but that may lead to overfitting. And in a case where 99% of observations have the same response, there is not much that one case do. You may want to generate the individual respo...

### Re: Ordered Logit Issue

In this type of model it is certainly possible that the highest predicted probability never matches the actual realization. This problem becomes more acute the greater number of possible outcomes in the speicfication. In this case, the highest fitted probability is always for the dep=1 category, und...
