Hello, This discussion of graphing an assumption versus a forecast variable and the example posted by Huybert have been very helpful and I wanted to post a...
Hello, I wanted to follow-up on the guidance offered by Huybert on graphing assumption-values (for one assumption) versus forecast-values (for one forecast). I...
Hi Derek, assuming you can't solve your problem analytically and assuming you have no 6D-monitor at hand, the best thing you can probably do is to hold ...

Hi I am a new user of CB and VBA. I hope the following aren't dumb questions but I would be grateful for any help. I have a model written in VBA. It is too...
Hi Andy! Those certainly aren't dumb questions at all. We all learn this by asking! As I understand what you're saying, it sounds like you need either the ...
Good morning. Earlier I saw a response from Hilary to a request that was what I also wanted to get - specfically how to get the parameters of this best fit...
Jimmy, If all that you need is the parameters that define the best fit distribution for forecast data, then all the you need to do is select Forecast > Fit...
