Maximum likelihood estimates of risk and ambiguity attitude determinants.

Each column shows the estimated coefficients and standard errors in parenthesis for different model specifications. luminance (hour) is the hourly average luminance level; luminance (day) is the daily luminance average; luminance (last 2 days) is the sum of the average luminance levels in the past two days. Higher ambiguity and risk estimates mean more risk and ambiguity tolerance.
