Low birth weight puppies present an increased risk of neonatal mortality, morbidity, and some long-term health issues. Yet it has not been investigated if those alterations could be linked to the gut microbiota composition and evolution. 57 puppies were weighed at birth and rectal swabs were performed at 7 time points from birth to 56 days of age....
Microorganisms of the gastrointestinal tract play a crucial role in the health, metabolism and development of their host by modulating vital functions such as digestion, production of key metabolites or stimulation of the immune system. This review aims to provide an overview on the current knowledge of factors shaping the gut microbiota of young d...
Questions
Question (1)
Hello everyone.
I have a question about VIP score. I am currently working on microbiota data, and I am using the mixOmics package on R to get VIP scores so that I can filter the most "important" taxa.
The thing is, I get one VIP score for each component of my PLS-DA, and I am confused about which score I should use in the end.
My first component is the one explaining the most variation, but I have been told the last component score takes into account the previous ones, so I should use this one.
On other studies, I saw they used the sum from each component to get a final VIP score.
In the end, I am quite confused about which one should be used.
Thanks for your answers.
