It is not particularly sensitive to deviations from this assumption. The assumptions that should be met to perform a one way anova. The function tests the hypothesis that the samples in the columns of y are drawn from populations with the same mean against the alternative hypothesis that the population means are not all the same.
Anova1 treats each column of y as a separate group.
For example suppose we had 7 groups. A one way anova analysis of variance compares the means of three or more independent groups to determine if there is a statistically significant difference between the corresponding population means. The number of pairwise combinations is 7c2 21. To do this you use anova analysis of variance.
