What Negative Kurtosis implies
Hi...I am new to data science, I have a dataset and when I am computing kurtosis of the Target Variable I am getting the value as -0.94. What I understand is a high kurtosis implies a Heavy tail of the data and low kurtosis implies light tail. What I can decide on this negative kurtosis?

Some functions will return Kurtosis after subtracting 3, for example the Excel KURT() function, whereas others do not subtract 3 by default. If you're getting negative values, the most likely explanation is you're using a function that subtracts 3 (the "excess"). Double check the function documentation or code to see if this is the case.
Good luck!

Dataset following normal distribution has kurtosis 0 after subtracting with 3. Negative kurtosis indicates the tail is flatter than that of normal distribution
