integrateDens | R Documentation |
Given a density function specified by the root of the density function name, returns the integral over a specified range, usually the whole real line. Used for checking that the integral over the whole real line is 1.
integrateDens(densFn = "norm", lower = -Inf, upper = Inf,
subdivisions = 100, ...)
densFn |
Character. The name of the density function to be integrated. |
lower |
Numeric. The lower limit of the integration.
Defaulty is |
upper |
Numeric. The upper limit of the integration.
Defaulty is |
subdivisions |
Numeric. The number of subdivisions to be passed
to |
... |
Additional arguments to be passed to |
The name of the density function to be integrated must be supplied as
the characters of the root for that density (e.g. norm
,
gamma
). The density function specified is integrated
numerically over the range specified via a call to
integrate
. The parameters of the distribution can be
specified, otherwise the default parameters will be used.
