Web1. Probably, Yes. Many times we need to regress a variable (say Y) on another variable (say X). In Regression, it can therefore be written as Y = a + b X; regress Y on X: regress true breeding value on genomic breeding value, etc. bias=lm (TBV~GBV) WebSep 9, 2024 · In this example, we have: Explanatory Variable: Type of fertilizer. This is the variable we change so that we can observe the effect it has on plant growth. Response Variable: Plant growth. This is the variable that changes as a result of the fertilizer being applied to it. Fun Fact: We would use a two sample t-test to perform this experiment.
