varstat3
algorithm
- calculates and plots histogram of distribution of variable1
- number of bars in histogram according to formula of Sturges;
- calculates and plots true pdf of distribution, pdf is based on 100 points
- calculates and plots gaussian pdf of distribution, pdf is based on 100 points,
- calculates mean value, standard deviation, skewness and kurtosis of distribution
syntax
