d_unifD: Probability mass function of the (discrete) Uniform Distribution

Description

Probability mass function of the (discrete) Uniform distribution with min $a$ and max $b$.

Usage

d_unifD(x, min = 0, max = 1)

Arguments

x

quantile. By definition, it has no impact on the uniform distribution. Set to 1 by default.

min, max

lower and upper limits of the distribution. Must be finite.

Value

Function :

• E_unifD gives the expected value.

• V_unifD gives the variance.

• d_unifD gives the density function.

• d_unifD gives the cumulative density function.

Invalid parameter values will return an error detailing which parameter is problematic.

Details

The (discrete) uniform distribution with min and max parameters $a$ and $b$ respectively has density: $$\text{Pr}(X=x)=\frac{1}{b-a+1}$$ for $x\in \{a,a+1,\dots ,b-1,b\}$.
