Nettet13. aug. 2024 · I tried to calculate the integral of the density of the normal distribution with expected value 200 and standard deviation 20. From -Inf to Inf this should be 1. I get the following: > integrate (dnorm, mean=200, sd=20,-Inf, Inf)$value [1] 1.429508e-08 For expected values below 169 I get the right value, 1. NettetIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ...
