WebA negative log means that we will use a negative exponent (power) when we convert from log form to exponential form. Remember that a negative exponent means that we are dividing by a number rather than multiplying. For example: 5 -2 = 1 / 5 2 = 1 / 25 That is, we are dividing by 25 instead of multiplying by 25. Web11 dec. 2024 · $\begingroup$ You would usually log-transform your data X if you can safely assume that the underlying probability distribution of Y = log(X) is normal; you can then use a linear model with normally distributed residuals for a downstream modelling/prediction analysis. The fact that you have negative values suggests to me that this is not the case.
