This procedure is suffice to test for the homogeneity of k regression coefficients (Ho: b1 = b2 =...= bk). The variability among the regression coefficients requires the F-statistic. If the null hypothesis is rejected, it can proceeds with a Tukey's q multiple comparision test to determine which of the k slopes differ from which other. If the null hypothesis is not rejected, the file test through a F-statistic whether they have equal elevations. Also, if the null hypothesis is rejected, it can employ a Tukey's q multiple comparision to determine the location of significant differences among the elevations. In addition, this file plot the observed data for the k samples.

It needs to input X-data matrix and alpha-significance level (default = 0.05).

It outputs a complete table that summarizes the used statistics for the procedures and its corresponding results.
