Very useful. Thanks for posting this video

Hello! I hope you are doing well. I am currently undertaking an interrupted time series analysis for my master's thesis, focusing on comparing the impact before and after the installation of two newly added mobile harbour cranes at a terminal starting in 2022. However, I am facing difficulties as the model I have employed is not effectively capturing the underlying patterns, resulting in a poor fit. Given the importance of accuracy in prediction for my thesis, I am concerned about proceeding with a model that does not adequately capture the patterns. Thus, I am reaching out to you for your assistance in resolving this matter. I have taken several steps to address the issue, including reviewing the model specification and ensuring the inclusion of relevant predictors and interventions. However, I believe there may be additional factors or variables influencing the outcome that I may have overlooked. Consequently, I would greatly appreciate any guidance or insights you can provide in this regard. Moreover, I am open to exploring alternative model specifications to improve the fit. I understand the significance of meeting the assumptions of interrupted time series analysis, such as linearity, independence, and homoscedasticity of residuals. I have conducted initial diagnostic checks, but the poor fit persists. As this is a critical component of my research, I am eager to seek expert advice. If you have any recommendations for experts in interrupted time series analysis or statisticians who could provide guidance specific to my research context, I would be grateful Thank you in advance for considering my request for assistance. Your expertise and insights would be invaluable in helping me achieve a more accurate and reliable prediction for my master's thesis. I look forward to your response. 😟

Thank you very much for the lecture. Very informative and useful. I really learnt a lot from that 🙏🏼🙏🏼

Thanks so much! Couldn’t understand a single thing I was reading

thank you so much, tho i wish i had the power point presntation

Hello, my research group really appreciates your video. We were recently introduced to the interrupted time series analysis, but we need more guidance from the faculty at our university. Would you happen to have any additional resources you can give me that I can share with my team on how to better understand the data and outputs for an interrupted time series?

Thank you very much for your sharing.

This was an amazing video- Thank you so much. How would the analysis be different if I have 2 different outcome variables to compare between 2 different groups? Do I first run the analysis for one variable for one group and then force the model for the other group for the same variable? And then repeat the same for the next variable? Or is there another way to conduct this? I hope this makes sense. Thank you so much

Excellent lecture. Very thorough. Would you please share your slides?

Hi! Thanks for the great tutorial. I am currently trying to analyze my data using interrupted time series. May i know, the model that you showed, which type of interrupted intervention pattern (step function or pulse function?). Thanks in advance!

very good lecture

Thank you for this

Thank you for your generosity in sharing this.

Sir i am doing a training of yoga vs aerobic in 20 traineers each with no control groups . I measure the progress after every 4 weeks for 12 weeks . Can i still used this ANCOVA methods as statistic

This is really useful, thank you! How do you force SPSS to show one of the variables in the model output even if it was non-significant?

Thank you very much, I learned a lot
