[@haliml]

Thanks for the explanation, Tim!

Incredible! Cant wait to use this!

Super helpful; great explanation. Thanks, Tim.

Thank you Tim for this very good video 😀

[@PatrickBateman12420]

Very cool Tim! Thanks for sharing. A few more updates, and Tableau feels like Python or R :-)

Aha yeah its getting complex but i like that it can remain simple as well. These are power features at the end of the day.

Hello Tim, this is super helpful thank you. Quick question, is there a way to forecast the Gaussian predictive model in Tableau? It's a calculated field so forecast function is greyed out. But if we have developed the GP prediction, how can we use it to predict the future months? Any help? Appreciate it.

[@navid8276]

I wanted to know this too! thank you!

[@Shashank42065]

It would be nice to see variety of examples for the same

[@robertwatson1369]

Hi Tim, super useful video and videos on your page Just wondered if you can calculate a predictive model on that data and then use that model on another set of data in tableau?

[@jeromevanbeek9070]

Hi Tim, was wondering how this really differs from the built in forecasting?

[@TableauTim]

You can customise it yourself with your own changed added in newer versions. The built in forecasting models are a specific set of forecasting libraries with no room for customisation.

[@DanielWeikert]

Can you elaborate on the ATTR Trick with some examples? Would be great. Thanks great video

[@TableauTim]

i noted it down as a video to make soon.

@@TableauTim Thanks... I've subscribed because of how responsive you are.

Video is live >> kzbin.info/www/bejne/qnWwlYuahrJ6jZY Thanks for the tip on the topic. Hope I did it justice here.

[@shellbell646]

Im confused. How is this illustrating predictive modeling vs a calculated trend line. Why I'm used to seeing is the time series extended to illustrate the "prediction"

[@TableauTim]

Valid point. I actually forgot to do the date extension which I called out at the very beginning and suggested you watch before this video. My main aim was to show the feature not explain the models so I thought the video still did that and unfortunately my schedule didn't allow me to rerecord the whole thing and re-edit the whole thing. As I suggest the dislike buttons there.

[@shellbell646]

@@TableauTim can you add that eventually. It will be really helpful..I didn't see much about it in the tableau documentation. Will keep looking. At least I have some place to start. Thanks for putting out your vids. They are wonderful

[@TableauTim]

@@shellbell646 sure the other video is here which shows the date extension. kzbin.info/www/bejne/eH-ynK15gLuUnKc

[@shellbell646]

@@TableauTim thank you. I will take a look.

[@PatrickBateman12420]

Valid point. However, going into the details gets extremely technical really fast. In SHORT: "trend line" is a simple linear regression based on two variables (x and y). Model quantile uses e.g. 0.5 (median) for interpolation (i.e., historical data). To extrapolate (i.e., forecast), it adds a linear regression.

Hello Tim, great content. New to tableau, do you have training courses on Udemy or any other platform for Tableu desktop specialist and Tableu certified associates certification?

[@TableauTim]

Not yet ;) Im actually redoing all my exams at the moment as they expired before I went on paternity leave so I'll be making a video covering them all. Stay tuned. There are some other videos though on KZbin.

[@tj6544]

@@TableauTim Thanks for the feedback. I will keep a look out and hello to the new family member.
