R2 value statistics

WebIs an r2 value of 0.9 good? How high an R-squared value needs to be depends on how precise you need to be. For example, in scientific studies, the R-squared may need to be above 0.95 for a regression model to be considered reliable. In other domains, an R-squared of just 0.3 may be sufficient if there is extreme variability in the dataset. WebR-squared (R2) is an important statistical measure. ... In that case, if there is a change in the independent variable in value, the other dependent variable will likely change in value, say …
