Time Series 101: Basic Notation Demystified Σ
Рет қаралды 4,618
Күн бұрынIn this Time Series 101 video, we start at the very beginning. Many students new to statistics, data science, and other related disciplines first see mathematical notation and run for the hills! In this video, I want to reassure students that understanding the notation is not too scary. We just need to break it down piece by piece. I hope you find it helpful. Keep on earning!

Yes, I enjoyed it a lot! Help me a lot in recollecting mental strength to look forward - issues related to 'moving average' and the 'lag'. Thanks a lot!

Brandon, a huge appreciation for all the content you have shared on your channel; I have to use time series forecasting to predict a Drought index : SEPI, I need to do it through the SVM. I really need to know will this playlist be relevant to my topic of interest?

Hello Brandon, one question regarding the video and moving average demonstrated. Since this is daily data how do you deal with a weekend in time series as trading in stock markets occur only on business days and data wouldn't be equally spaced in time. Maybe a hint or keyword so I could do my own research ion this? Appreciate your videos a lot. Thank you!

You would still treat them as daily, but as trading days not weekdays. Weekends and holidays would be ignored. But it might be beneficial to keep track of the day of the week as a separate variable.

Gréât vidéo … I have a question on ANOVA(I asked my question on one of your ANOVA video but I could not have a reply) 1) Is it possible to carry on a One Way ANOVA .. with groups of with different total number of data points ? 2) Is it possible to to do a «TWO WAY ANOVA with replication », where the total number of values in each cell is different across the different groups of the table? It will be helpful to have an answer. Thanks.

Hello! Yes both are _possible_ however not recommended as it can cause issues with interpretation, variance, and degrees of freedom. Also remember that pretty much any ANOVA can be run as a regression, but the interpretation is different. If you want to run unbalanced ANOVA, most modern software can handle it, except Excel.
