Answer by Martin Wettstein for Model that takes two percentiles as input - what is the percentile of the output value

If you know the 50th percentile and assume normal distribution of the input, then you already know the mean value of that distribution. The standard deviation can be computed, knowing that the 90th and 10th percentile have a distance of 1.28 standard deviations from the mean.So, you have a completely defined normal distribution with these informations. You can use them to simulate the input in the programming language of your choice and use them as input to your analysis to get the outputs.

## R code:input = rnorm(1000,mean,sd) ## 1000 cases with this mean and sd## Python codeimport randominput = []for _ in range(1000):    input.append(random.gauss(mean,sd))
