MATLAB: Lognormal distribution between a specific range

Question

Hello, I am trying to create a lognormal distribution using the 'lognrnd' command between 3000 and 10000

I want the distribution to be skewed to the right as that is the characteristic of lognormal distributions.

I attempted several times to create the distribution using the mean and the standard deviation of the associated normal distribution spread between 3000 &10000 but when I plot the histogram of the generated lognormal distribution, the distribution still looks like a normal distribution without skewness.

Any help is appreciated.

thanks

Answer 1

Here is some code that does roughly what you asked for.

r = lognrnd(8.6,0.2,100000,1);
figure
histfit(r);
skewness(r)

The red curve is the normal curve fit to the randomly generated data. The skew is evident, with a skewness of about 0.6.
