This function is based on tabularized Dixon distribution, given by Dixon (1950) and corrected\nby Rorabacher (1991). Continuity is reached due to smart interpolation using qtable function.\nBy now, numerical procedure to obtain these values for n>3 is not known.

"],"value":"\n\n

Critical value or p-value (vector).
