p {bruceR}

Compute p value.

Description

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
)

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, \chi^2 value.

n, df, df1, df2

Sample size or degree of freedom.

digits

Number of decimal places of output. Defaults to 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 \chi^2. (Note: \chi^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)
