| May 5, 2022 at 2:32 | comment | added | whuber♦ | @user20650 is correct--but the point is moot in this example, because the expected counts are all less than 5, too. But combining bins post hoc can lead to invalid p-values. Moreover, warnings should be taken seriously: they are not automatically "allowable." Sometimes they're ok--but you should know why they can be ignored. | |
