Hey Frances – We admit We haven’t been following the current books with the money, but equivalent things develop within the study off medical care expenses, perhaps even significantly more really. Healthcare expenditures are a problem regarding the U.S. as there are a great amount of files into the talking about a leading ratio off zeros and you may tall skewness about non-zero observations on these analysis. Not accurately my city, but when I be able to stay awake an individual was giving a methodological paper to the health expenses I collect one finite mixtures are preferred these days, with double hurdle and other alternatives-type of habits. GLM steps are quite common, that is strange during the econometrics.

Chris: I would personally slightly joyfully agree that normality and you will heteroskedasticity aren’t the real problems with OLS quite often; the rates is as much as right, and you will objective, as long as the actual dating is actually linear

however, I’d say while you are selecting inference regarding beliefs close zero, zero level of data’ll help save you on the undeniable fact that « my personal design are anticipating bad ten-thousand bucks away from riches of these somebody, while they are in reality at no. »

Frances: How about generalized additive designs to have non-linearity? Your treat somewhat versus OLS otherwise GLM given that you cannot overview the latest model having a desk off coefficients.
