Statistical properties of radial distributions

Receptor	Mean	Variance	Skewness
fZOR6	0.226	0.0181	1.08
	(0.206 to 0.241)	(0.0112 to 0.0244)	(0.818 to 1.30)

	(0.342 to 0.366)	(0.0192 to 0.0236)	(−0.109 to −0.0290)
fZOR8	0.414	0.0248	−0.454
	(0.396 to 0.437)	(0.0226 to 0.0271)	(−0.770 to −0.210)
fZOR5	0.456	0.0255	−0.858

The radial distribution of labeled cells was determined for individual epithelia for each of the four receptors fZOR6, fZOR9, fZOR8, and fZOR5. Mean, variance, and skewness of these distributions were obtained. Expectation values for these parameters, together with 95% confidence intervals (in parentheses), were obtained by bootstrap analysis. Nonoverlapping confidence intervals indicate a difference significant at P < 0.05. Note that values for the means differ from the frequency peaks seen in Fig. 4, a necessary consequence of the asymmetry of the observed distributions.
