c2GOF c2GOF obsList,expList,df chi2GOF obsList,expList,df Performs a test to confirm that sample data is from a population that conforms to a specified distribution. A summary of results is stored in the stat.results variable. (See page 76.) Output variable stat.c2 stat.PVal stat.df stat.CompList Description Chi square stat: sum((observed - expected)2/expected Least probability at which the null hypothesis can be rejected. Degrees of freedom for the chi square statistics. Elemental chi square statistic contributions. c2Pdf() c2Pdf(XVal,df) ⇒ number if XVal is a number, list if XVal is a list chi2Pdf(XVal,df) ⇒ number if XVal is a number, list if XVal is a list Computes the probability density function (pdf) for the c2 distribution at a specified XVal value for the specified degrees of freedom df. clearAZ clearAZ Clears all single-character variables in the current problem space. Catalog > Catalog > Catalog > ClrErr Catalog > ClrErr Clears the error status and sets system variable errCode to zero. For an example of ClrErr, See Example 2 under the Try command, page 84. The Else clause of the Try...Else...EndTry block should use ClrErr or PassErr. If the error is to be processed or ignored, use ClrErr. If what to do with the error is not known, use PassErr to send it to the next error handler. If there are no more pending Try...Else...EndTry error handlers, the error dialog box will be displayed as normal. Note: See also PassErr, page 58, and Try, page 84. Note for entering the example: In the Calculator application on the handheld, you can enter multi-line definitions by pressing @ · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter. TI-Nspire™ Reference Guide 13
