Hypothesis Testing

Goodness-of-fit tests such as Chi-square, Kolmogorov-Smirnov, Shapiro-Wilk, and t-test

MuPAD Functions

stats::csGOFTClassical chi-square goodness-of-fit test
stats::equiprobableCellsDivide the real line into equiprobable intervals
stats::ksGOFTThe Kolmogorov-Smirnov goodness-of-fit test
stats::swGOFTThe Shapiro-Wilk goodness-of-fit test for normality
stats::tTestT-test for a mean

Examples and How To

Perform chi-square Test

For the classical chi-square goodness-of-fit test, MuPAD® provides the stats::csGOFT function.

Perform Kolmogorov-Smirnov Test

For the Kolmogorov-Smirnov goodness-of-fit test, MuPAD provides the stats::ksGOFT function.

Perform Shapiro-Wilk Test

The Shapiro-Wilk goodness-of-fit test asserts the hypothesis that the data has a normal distribution.

Perform t-Test

The t-Test compares the actual mean value of a data sample with the specified value m.


Principles of Hypothesis Testing

Hypothesis (goodness-of-fit) testing is a common method that uses statistical evidence from a sample to draw a conclusion about a population.
