Note: Long-stay is defined as staying at a nursing home for more than 20 days following admission. The likelihood of becoming a long-stay resident has been estimated using a linear probability model and explanatory variables listed in Table 1 and primary diagnosis ICD9 fixed effects.

All the regressions have total number of beds, occupancy rate, case mix index, and their interaction with black as additional independent variable.

Robust z-scores are in the brackets.
