I got this equation by predicting grassland biomass growth from precipitation and soilnutrient. How can I convert it into original power function and how to interpret scientifically.

logNDVI <- 0.36 + 64.8*log(precipitation) + 0.9*(soilNutrient)

P <- 0.01; R2= 0.72 and residual standard error=0.45

Thank you!

  • Please explain what you mean by "original power function." Do you mean that logNDVI is the logarithm of observed biomass growth and you wish to express the corresponding growth directly in terms of precipitation and soilNutrient?? – whuber Jun 25 '19 at 14:01
  • I mean that how to convert this log transformed formula into the one without log with exp() function. – Sun Rise Jun 25 '19 at 15:19
