To find kurtosis for data and normal distribution ("Gaussian distribution" is synonymous with the normal distribution) use the following codes:

example: RQ: this is data for patients who have VT disease and then we created itervention cohort ICM and control arm had NICM.

continuous variable "age"

Binary variable "icm_nicm"

STATA Code as below: this below code is to find summary / descriptive statistics and kurtosis:

by icm_nicm, sort: summarize age, detail

This below code is to make histogram:

histogram age, normal kdensity kdenopts(gaussian) by(icm_nicm)

kurtosis >3 is not normally distributed
