ttest
One-sample and paired-sample t-test
Syntax
Description
returns
a test decision for the null hypothesis that the data in h
= ttest(x
)x
comes
from a normal distribution with mean equal to zero and unknown variance,
using the one-sample t-test.
The alternative hypothesis is that the population distribution does
not have a mean equal to zero. The result h
is 1
if
the test rejects the null hypothesis at the 5% significance level,
and 0
otherwise.
returns
a test decision for the paired-sample t-test with
additional options specified by one or more name-value pair arguments.
For example, you can change the significance level or conduct a one-sided
test.h
= ttest(x
,y
