I am doing reserach on behavior analysis, and doing statistical analysis to see the effects of factors across different neighborhoods. For that I need to conduct multilevel tobit regression analysis on my (censored) behavior data. Is there any R package that can support multilevel tobit analysis? I googled a lot, but could not find any (only found that stata 15 supports this). But I prefer using R and would very much appreciate it if sb can provide any info. Thanks!
