Tools:Mainly StataSome R

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?
