LOGINV(prob,m,sd)
- is the probability associated with lognormal distribution
- is the mean value of ln(x)
- is the standard deviation of ln(x)
is the probability associated with lognormal distribution
is the mean value of ln(x)
is the standard deviation of ln(x)Description
- This function gives the inverse value of lognormal cumulative distribution.
- This distribution is the continuous probability distribution.
- Lognomal distribution is also called Galton's distribution.
- A random variable which is log-normally distributed takes only positive real values.
- If LOGNORMDIST(x,m,sd)=prob, then LOGINV(prob,m,d)=x.
- This function will give the result as error when
- Any one of the argument is nonnumeric.
- prob<0 or prob>1 or sd<=0
Examples
- LOGINV(0.039084,3.5,1.2)=4.000025219 (EXCEL)=3.9957031(CALCI)
- LOGINV(0.24786,6.25,3.12)=61.83892171 (EXCEL)=NULL(CALCI)
- LOGINV(0.007543,5.82,2.9) =0.292909096(EXCEL)=NULL(CALCI)
