Is there a reason why after adding a new observation to my data I cannot use the new observation for the forecast range? On the main Gretl data window, the full range shows that the new observation has been added. However, when going to Analysis > Forecast > Forecast Range, I cannot increase the range to reflect the new full range (with added observation). Any ideas as to why? Any ideas/suggestions much appreciated!
hi, someone can explain how to remove seasonality from a time series (daily frequencies) ? And how to test whether seasonality has been indeed removed? (a part of ADF and KPSS test)
Hi! Thank you very much for your video. What should i do if I want to study the relation between Xt and Xt-1 ( Xt = a + bXt-1 + e ) ? I don't really know how to create the value for the previous day. im trying to graph electricty sales but cant seem to make it work, maybe you might know. Thanks :)
Thanks for a wonderful presentation. i found this vedio useful. i downloaded the gretl software from google and am forecasting residential estate price using arima. At the end the forecasting model shows some figures with negative sign instead of residential price as it is in my data. so i couldnt understand why and i cannot interpret it. am expecting to see the price in Y axis and years in X axis. Moreover at the end of the forecast it also cannot show forecast evaluation.
Sorry it shows something like this in the graph in Y axis like 2.8e+007 , 2.6e+007, 2.4e+007, 2.2e+007, 1.8e+007..etc. It didnt show me the price of real estate as it is in my data and as i see in your forecasted model. Thanks
Future forecast does not work according your instructions. Added observations, predictions keep saying I have to add observations. Changed range, predictions keep saying I have to add observations. I literaly did everything step-by-step according your video and still... not working. I keep waving magic wand. Same result.
Thank you a lot. I lost a lot of time on study project. You are a saver!
I love your presentations. They are crystal clear. Thank you so much!

Hello, may I understand why "January" is deleted from the equation?
Thank you! Very helpful and clear all the way!
Thank you for such a clear and simple demonstration!
Thank you! I have one question : if the time-series that we use are not stationary, do we need to make it stationary before forecasting ?
yes
Why is my periodic dummy isn't click-able? Can someone please give the explanation? thanks
Can u make a video for trend analysis using gretl n the mann Kendall test
