the two side one is already implemented in Matlab by nctcdf. I am interested to the one-side one because i need to find the characteristch value with a certain level of confidence. if this is expressed as k-times the st.dev from the mean, x=mean+k*st.dev, this means for instance to find k so that we are 75% confident that 95% of the population lies below x,
does anyone know how to do that?
