9:18 then then then then 😅😅

Thank for useful video

Good video

Thank you

Wooow. I will definately get a 60 out of 60. Our Quantitative Methods in Human and Social Development lecturer gave us an assignment on the IHDI worthy 60 marks. Your explanation is just extra superb and straight to the point. Your IHDI example calculation has soothed my headache.. 😊😊😊😊😊😊😊. Thank you. Do more videos pliz....

Could someone help , what code should I use to make my age variable that contains ages from 0-11 into groups of categories? I want the first age group be from 0-2 , the second 3-5 the third 6-8 and the forth 9-11

Very simple way to learn. Thanks a lot.

Very interesting presentation Sir. I just completed a survey on consumer tipping behaviors in the tourism and hospitality industry in Cameroon for my Ph.D. thesis dissertation. The first part looks at the determinants that influence people to tip or not tip (dependent variable; binary=tip or not). Here, I have no issues implementing a probability approach. But in the second part, the objective is to see the factors that influence people to tip more (tip size/amount), and the dependent variable is continuous. In this second part, the focus is solely on those who tip. My worries are: 1. After running the OLS, Simple Tobit model, and truncated Tobit, I need to carry out the Heckman selection bias test, and when I do this test: a) By including twostep at the end of Heckman's command, Lamda isn't significant b) When two-step is not included at the end of the Heckman selection command, the model is very significant and good 2. What do I need to do? do I retain the (b) for interpretations by considering lnsigma or what do I do with (a) to have consistent results? I will really appreciate your help at this point Prof

Can you please give an example of how it exactly happened?? Give a real example in ihdi

nice explanation but How can I get your address please?

Many thanks for your clear explanation,

Darun

Thanks a ton sir ❤️

Thank you , most grateful

Hi, Thankyou for this lecture. Can you please guide on how to estimate/predict the value of wages in this model if we take dependent variable as logWage.

Can I use this model for categorical dependent variable? Let me explain briefly, One dependent variable is whether people consume or not (consume =1, not consume =0) and Another one variable is how frequently they eat in a year (consume daily or weekly =1, consume once a month =2, consume rarely=3). Independent variables are demographic factors, psychological factors, social factors and product related factors.

hi Mr Shishir really i am enjoyed on your presentation and i am going to carry study on farmers perceptions of and adaptation to climate change. would you recommend any,,,,,,,,,,,

Thanks a lot bro!

Hey Shishir, great video! Thanks so much for detailed explanation. I would like to ask a question about using Heckman selection correction to control for self-selection bias. I have been doing a survey study with participants from social media sites (e.g., Twitter/ Facebook). I reached out to 500 people on social media and only received 200 responses. Because of the low response rate, I would need to correct the selection bias introduced by the low response rate. I tried to use SPSS and STATA to do the test. In the first stage of the analysis, a probit regression needs to be used to estimate the likelihood of users not participating in the survey. However, I do not have data for non-participants (as they did not respond to my invitation). Thus, the selection model is of no use because the selection dependent variable is participation status, a binary variable that accounts for participation vs. non-participation. My questions are as follows: 1) Can I use the Heckman selection correction to control for self-selection bias? If so, how do I run the selection model when the data for non-participants are unavailable? 2) Are there any other ways to address self-selection bias in an online survey study such as mine? 3) Does Heckman's correction apply to logistic regression or ordinal logistic regression? I realised its second step model is a linear regression but my dependent variable is a binary one (hence logistic regression). Many thanks for answering my questions. Much appreciated!

In probit regression if the Prob > chi2 = 0.513 then what does it means.. is my model not significant or it is called different type of significance. basically what does it means..?

Thank you Sir.

Very informative, Thanks!! Looking forward for more videos. It would be great to have it in a log/smcl format.
