If the fitted values of a quantile\nregression on this transformed outcome are all greater than the\nnegative value, then results are displayed. The resulting\ncoefficients can be meaningfully interpreted as logarithmic\nintensive-margin relationships between the outcome variable and\nthe independent variables, even with non-positive values in the\noutcome variable. If the condition does not hold for the\nspecified quantile, then the command iteratively makes the\nvalue larger and checks again. After ten iterations where the\ncondition does not hold, the functions return an error and\nsuppress results. This is an automated adaptation of the\nalgorithm described by Liu & Kaplan (2025)\n\nand implemented in the companion 'Stata' command 'lzqreg',\ndescribed in Fitzgerald et al.
