  1. Woww!!
    This is a lovely platform. I trust what you can do. I believe this platform will also work together with Eduresearch.ng to improve the research skills of students and researchers in different field of study.

    1. I believe so too. We are here to teach the rudiments of econometrics (see BLOGPOST), encourage readers to engage in data analysis and also show the practical applications of using Stata analytical software with exciting videos….watch out for our YouTube videos!

    1. Yes, you are right that is the objective of setting up this site to demystify data analysis and the use of econometrics. We will appreciate if you can refer students to this blog so that they can follow the simplified tutorials, post their questions and other challenges relating to econometrics….and also attempt the assignments for better understanding of the applications of econometrics.

  2. This blog is long overdue. Crunch econometrix is set to demystify the monster in research called data analysis and interpretation. It’s a welcome development.
    Kudos to the Tutor.

    1. Thank you very much for the words of encouragement. You are encouraged to refer students to this site to enable them follow the simplified lecture tutorials on the blog. Simply click on BLOGPOST

  3. @ Engee thanks for this given back spirit in you, highly inspiring!
    Please how does the lecture follow? Or each independent of other? Because Heteroscedasticity came on Jan 8., follow by Multicollinearity, then Tell me, what is econometrics? Just for some of us starters in econometric worldview to be well grounded as we get along your laudable philanthropic teaching.

  4. Hi Gbenga, hope you’re doing ok. The lectures do not follow any particular order, they are independent of one another. But where lectures are inter-related, I will then prepare such tutorials in their almost particular order. For instance, I just posted on the one-way ANOVA (analysis of variance) procedure….and in the next couple of days, the two-way ANOVA procedure will be posted. This is because, it is important to understand the one-way ANOVA before gravitating to the two-way, three-way and so on.

    Also, readers often suggest some topics like two out the five posts are topics suggested by them (that’s http://cruncheconometrix.blogspot.com.ng/2018/01/heteroscedasticity.html and http://cruncheconometrix.blogspot.com.ng/2018/01/multicollinearity.html). So, you can always suggest any topic that require some simplified explanations.

    If I may ask: are you acquainted with any analytical software? Even I though I teach using the Stata application, I post datasets in excel files too so that readers can download and feed into any application of their choice to practice along as I teach. Which one are you using? Please let me know, thanks!

    1. Thanks so much @ Engee!
      Actually reason why I asked is because am just trying to learn econometrics and how to go about modelling. I’m a research student in psychology and I do analysis, and of recent some Agric Econs student seek my guide in econometric analysis which I don’t too know and I decide to do self-learning, I so much appreciate your passion and wish to grab sound knowledge in econometric from your expertise.
      I use SPSS, trying to learn “r” and will appreciate knowing Stata. Regards!

      1. Good to know that you are on track. The basics of econometrics are the same regardless of the analytical software. I’ll definitely help you out with using Stata. I’ll soon be doing some videos on the rudiments of using Stata. They are quite easy to grasp… just stay with me on this platform and I will do my best to teach the little I know to as many who are willing to learn a thing or two. Take care…

    1. Yes you can. But remember that cointegration implies that the series are related and can be combined in a linear fashion. So you can estimate a VECM and Granger causality. But if there is no cointegration, It implies that there is no long-run relationship so only the short-run model will be estimated. I hope this is helpful.
      Good luck with your research!

    1. Hi Liz,
      There’s the Human Capital Theory of Becker and Tomes (1979, 1986). It states that the decision of parents to invest in their children’s human capital development determines the extent of persistence of relative incomes across generations. The simple interpretation is that education reduces income inequality gap. As more people become educated, they are able to get better jobs and better incomes….read more on this online.

  5. Kindly upload a complete video lecture on Gregory and Hansen Cointegration Test with Structural Breaks using Eviews. It will be of a great help.

  6. Good day, please can you run a time series analysis with some missing observations in a particular data set? for example, if i have a time series data on exchange rate for Ghana and in some of the years i do not have data available for exchange rate, can i go ahead and run my estimation with what i have or i will have to fill the empty spaces before i do my estimation? thank you.

  7. Hi Nii, sincere apologies for the late response. Results from time series estimates are biased if the number of observations falls below 30 years (small sample bias). Unless, you are certain that after accounting for the missing data, obs>30 then you can go ahead, Otherwise, you need to drop the exchrate variable and find another proxy.

  8. Thanks for this insightful peace. Am not happy that I didn’t know of you or the site for long, but nevertheless am happy to find this site now. Thank you once again for the knowledge you share with us.

  9. Good afternoon admin… Thanks for your videos it has help me a lot. I am running an ARDL model and my stata can’t recognised the command (ardl) please can you help me

    1. …thanks Richard for the kind remarks. Humbly appreciated and kindly tell others too. Kindly post the error message you are getting on the comment section of the YouTube video that will aid in assisting you appropriately. Thanks.
