he Majority Phase in Count Data

Hello,

I have a dataset consisting of counts across three phases: p0, p1, and p2. Here's an example:

Contig  p0  p1  p2
cont1   1   7   3
cont2   9   2   3
cont3   1   2   7

I want to determine the predominant phase for each row, i.e., the phase with the highest count. For instance, in row 1, it's phase p1.

What statistical test can I use to select the majority phase? I'm looking for a method that considers the count distribution across all three phases and helps identify the phase with the highest count in a statistically significant manner.
