Help with econometrics and/or Stata
How do I bootstrap estimates from survey data?
Stata does not support weighting for the type of graph I want to create. Can you help?
I want to study the factors underpinning scholar migration. What identification strategies would you suggest?
I have two datasets and I want to merge them. However, there are not unique case ID’s in either. What would you recommend?
I have a large and highly sensitive dataset stored in a SQL database. Can you help me access the database directly from within Stata?
Help with computation/estimation
I am trying to estimate a model but for some reason the routine fails. Could you have a look at my script ?
I am working with a large dataset and my machine is giving up on me. Do you have any suggestions?
Which estimation method is best for…?
Re-normalized Multinomial Logit
Common normalization in multinomial logit
Patron:
• Doctoral Student, Department of Economics
Goal:
• Estimate multinomial logit model with non-standard normalization
But what if different normalization is needed?
