Probability Functions
Logistic Quantile
Returns the quantile associated with a cumulative probability p of the logistic distribution with location mu
and scale sigma.
Loglogistic Density
Returns the density at x of the loglogistic distribution with location mu and scale sigma.
Loglogistic Distribution
Returns the probability that the loglogistic distribution with location mu and scale sigma is less than x.
Loglogistic Quantile
Returns the quantile associated with a cumulative probability p of the loglogistic distribution with location
mu and scale sigma.
Lognormal Density
Returns the density at x of the lognormal distribution with location mu and scale sigma.
Lognormal Distribution
Returns the probability at x of the lognormal distribution with location mu and scale sigma.
Lognormal Quantile
Returns the quantile associated with a cumulative probability p of a lognormal distribution with location
mu and scale sigma.
Normal Density
Accepts a quantile argument from the range of values for the standard normal distribution. It returns the
value of the standard normal probability density function (pdf) for the argument. For example, you can
create a column of quantile values (x) with the formula count(-3, 3, nrow()). A second column is computed
as Normal Density(X) to generate density values. Then select Graph > Overlay to plot the normal density
by x.
Normal Distribution
Accepts a quantile argument from the range of values for the standard normal distribution with mean 0 and
standard deviation 1. It returns the probability that an observation from the standard normal distribution is
less than or equal to the specified quantile. For example, the expression Normal Distribution(1.96) returns
0.975, the probability that an observation from the standard normal distribution is less than or equal to the
1.96 th quantile. Also, you can specify mean and standard deviation parameters to obtain probabilities from
nonstandard normal distributions. The Normal Distribution function is the inverse of the Normal Quantile
function.
