onesampsgn: One-Sample Sign Analysis

In joemckean/mathstat: Introduction to Mathematical Statistics R Package

Description

Calculates a distribution free confidence interval for a sample median by deriving for the 100pth distribution percentile of a continuous random variable. .

Usage

onesampsgn(x, test = FALSE, alt = 0, theta0 = 0, alpha = 0.05,
  maktable = TRUE, plotb = FALSE)

Arguments

x	Sample of size 'n'
test	Computes a two-sided sign test about theta0. If test is true, then H_0: theta = theta0 vs. H_1: theta != theta0 is conducted.
alt	Computes a one-sided sign test for theta0. If alt equals 1, then the test H_1: theta > theta0 is conducted. If alt equals -1, then H_1: theta < theta0 is conducted.
theta0	Variance of sample x
alpha	Level of significance
maktable	If true provides more descriptive output for x
plotb	If true a boxplot is produced

Details

Computes the solution to Example 1.3.3 (8th Edition)

Value

The probability bday of at least two people having the same birthdays
