ttest1
Purpose
One sample t-test.
Synopsis
result = ttest1(x,mu,test)
Description
Calculates a one sample t-test for sample (x).
Inputs:
x = The name of a matrix
(column vector) in which the sample data is stored.
mu = scalar, the null hypthesis
value for the mean {default = 0}.
ttest = [-1,{0},1] indicates what
ttest is for:
-1 - lower
tail H0: mean(x) <= mean(y)
0 - wo-tail H0:
mean(x) ~= mean(y) {default}
1 - upper
tail H0: mean(x) >= mean(y)
Outputs:
The output (result) a structure with the following fields:
t
= test statistic.
p
= probability value
mean
= mean of x
var
= variance of x
n
= length of x
se
= standard error
df
= degress of freedom
hyp
= hypothesis being tested
Examples
result = ttest1(x);
result = ttest1(x,mu);
result = ttest1(x,mu,test);
