Is there a way to drop lines other than the _cons line? I am trying to plot the results of a logistic regression with several control variables, and when I use the code as shown here ALL of the control variables end up in the plot, which I don't want.
Yes, But you have categorical variable, then you have not to use i.X or ib1.X , etc. In this case, please create dummy variables. for example use "D:\abc\MyData.dta", clear logistic bmiCAT ib0.toilet2 ib1.anc2 ib5.v190 v012 tab v190, gen(v190) logistic bmiCAT ib0.toilet2 ib1.anc2 v1904 v1903 v1902 v1901 v012 coefplot, drop(_cons v1904 v1903 v1902 v1901 v012) xline(1) eform Data Source: github.com/ahshanulhaque/MyData/raw/main/MyData.dta

Amazing vidéo Thanks
After comp1, is the procedure the same for all other components?
@@aklimakhatun1530 Yes, if you need 2nd or 3rd, then type predict comp2 comp3
For clear understanding I have a few questions? Let's say, I have 3 groups of intervention and one group is control. 1. Since the sample size is 117 here, do I have to have 117 participants in each group or it is 117/4 ? 2. And is the calculation always comes like 117 or it depends on power of the study? 3. To get a larger sample size what would be the formula?
Thank you. Using this method, we will get sample size for one group. Then we have to multiply by number of groups (n=n1*3)

Great video. Thanks so much. My question is why "predict comp1" only? What if comp2 and comp3 have eigen values greater than 1, do we also run the "predict comp2" and "predict comp2" command.
please i have this message : estat kmo correlation matrix is singular
Thanks! This is actually simpler than I anticipated it to be. Great work! I will try it out. However, I was wondering, do you not think that we are losing a nuance in the data by converting it into a binary variable? For example, maybe there's some important information between "having an item (1) and not having that item (0), which is most likely lost when categorising into a binary variable?
First of all, thank you so much for this video!!!, it really helped that it wasn´t edited so I could understand all the process of analyzing case-control data. Im new in the field of data analysis and biostatistics, but I have rather a silly rookie question why OR doesn't appear in No smoking, Rural, Normal BMI, Female and Service holder? Also would you mind showing how to do a OR Forest Plot for this data? It would be really helpful
I love it especially for education purposes
