Relative frequency distribution of FSGS variants in 50 adolescents and its comparison with young children at our center.19

Cumulative and relative frequency distribution of the sample according to gender:

Cumulative relative frequency distribution of the sample according to age:

The variables examined were: cross sectional area (CSA) of each fiber type,

relative frequency distribution (F) of each fiber type per microscopic field analyzed and relative cross-sectional area (RCSA) that a fiber type occupied in the biopsy specimens.

The data for each variable is depicted in Figure 2 by using a relative frequency distribution. The histogram for the oil price index shows an irregular (plurimodal) distribution with four distinct modes, but all of them showed normality.

The relative frequency distribution of differences between consecutive terms (Figure 6) shows that data for volume approach normality, but not that for prices.

While the index we present below is also based in part on cumulative relative frequency distributions (as in Lorenz analysis), our interest in relative incidence (i.e., proportional representation) and the relative frequencies of groups at each level--which does not form a proper relative frequency distribution over the hierarchy--does not lend itself to a Lorenz approach, which requires true joint cumulative relative frequency distributions.

However, comparative state analyses that seek the effect of group distribution over the hierarchy, independent of possibly confounding effects of the shape of the hierarchical structure itself, might best be carried out by making the [c.sub.i] the same across states--perhaps by using the cumulative relative frequency distributions for the combined states.

Relative frequency distributions of the ratios of standard deviations of scores and the ratios of standard deviations of the corresponding ranks are plotted in Figure 1, for normal distributions with N = 100.

Figure 2 plots relative frequency distributions of the scores and ranks themselves, over all 50,000 replications.
