Webb16 maj 2024 · For this reason, researchers frequently use the natural log of market capitalization. Here's a part of Table 9.1 As you see, market cap is very skewed and has an enormous kurtosis (fat tails). This is due to some outliers with huge market cap (firms like Apple skew the entire distribution). Taking the log standardises the variable somewhat. WebbIt is mathematically expressed in the following mathematical form in calculus. lim x → 0 ln ( 1 + x) x. Actually, the limit of this type of rational function is equal to one as the input of the function tends to zero. lim x → 0 ln ( 1 + x) x = 1. This standard result is used as a formula while dealing the logarithmic functions in limits.
