NORMAL= normal distribution for standardizing fit = No, chi-square

The standard generally matches the statistics used in BTD and RSA.

 

Specifies whether distribution of squared residuals is hypothesized to accord with the chi-square or the normal distribution. Values of t standardized fit statistics are obtained from squared residuals by means of one of these distributions.

 

NORMAL=N

t standardized fit statistics are obtained from the squared residuals by means of the chi-square distribution and the Wilson-Hilferty transformation (the standard).

NORMAL=Y

t standardized fit statistics are obtained from the squared residuals by means of an asymptotic normal distribution (F.A.G. Windmeijer, The asymptotic distribution of the sum of weighted squared residuals in binary choice models, Statistica Neerlandica, 1990, 44:2, 69-78).
