In the past I  had to calculate the probability that an observation from the standard normal distribution is less than or equal to x and I used the probnorm function. Now I have to calculate the same for a skew-log-normal distribution. How can I do?

Thank you for any help.

I'm not sure what parameterization you have for your skewed lognormal distribution, but try the CDF function, which supports the lognormal distribution.

In general, you should stop using the old PROB* distributions and switch to the newer CDF distribution, which sometimes supports a wider range of parameter values (for eexample, very small or very large parameter values).

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
