## Compute p value.

Compute p value.

### Usage

```p(
z = NULL,
t = NULL,
f = NULL,
r = NULL,
chi2 = NULL,
n = NULL,
df = NULL,
df1 = NULL,
df2 = NULL,
digits = 2,
nsmall = digits
)

p.z(z)

p.t(t, df)

p.f(f, df1, df2)

p.r(r, n)

p.chi2(chi2, df)
```

### Arguments

 `z, t, f, r, chi2` z, t, F, r, χ^2 value. `n, df, df1, df2` Sample size or degree of freedom. `digits, nsmall` Number of decimal places of output. Default is `2`.

### Value

p value statistics.

### Functions

• `p.z()`: Two-tailed p value of z.

• `p.t()`: Two-tailed p value of t.

• `p.f()`: One-tailed p value of F. (Note: F test is one-tailed only.)

• `p.r()`: Two-tailed p value of r.

• `p.chi2()`: One-tailed p value of χ^2. (Note: χ^2 test is one-tailed only.)

### Examples

```p.z(1.96)
p.t(2, 100)
p.f(4, 1, 100)
p.r(0.2, 100)
p.chi2(3.84, 1)

p(z=1.96)
p(t=2, df=100)
p(f=4, df1=1, df2=100)
p(r=0.2, n=100)
p(chi2=3.84, df=1)
