The following
To Define Data Sets
- numbersets: number of data sets to generate
- Parameters that can be set for each data set. The parameter will be
in the form "paramX" where X corresponds to the number of the data set.
- title: title for the set, default = "Set X"
- n: number of data points, default = 20
- datadef: instructions as to how the data set is to be formed
- Explicit list of data.
datadefX = list
data must be a comma delimited list of numbers in the parameter "dataX"
- Randomly generated values drawn from normal sample with explicit mean
and standard deviation
datadefX = normal,Mu,Sigma
- randomly generated values drawn from a uniform distribution
Default action
API for external access to data statistics
In order to get statistics on a particular set you will need to specify
which set you want. The data sets are numbered from left to right
beginning with 1.
- double getMean(K)
- returns the Mean of data set K
- double getSumX(K)
- returns the Sum of values from data set K
- double getSumXSqr(K)
- returns the Sum of squared values from data set K
- double getStdDev(K)
- returns the standard deviation of data set K
- double getTCrit1Tailed(df, alpha)
- returns 1-tailed tcrit for "df" degrees of freedom and alpha
- double getTCrit(df, alpha)
- returns 2-tailed tcrit for "df" degrees of freedom and alpha
- double getConfIntLower(which, alpha)
- returns lower bound of confidence interval for data set "which" and
level alpha
- double getConfIntUpper(which, lev)
- returns upper bound of confidence interval for data set "which"
and level alpha
- double getGrandMean()
- returns grand mean of all data sets combined
- double getSSWithin()
- returns the Sum of Squares within
- double getSSBetween()
- returns the Sum of Squares between
- double getSSTotal()
- returns the Sum of Squares total
- double getMSWithin()
- returns Mean of Sum of Squares within
- double getMSBetween()
- returns Mean of Sum of Squares between
- double getTotaldf()
- returns overall degrees of freedom
- int getBetweendf()
- returns d.f. between = NumberSets-1
- int getWithindf()
- returns d.f. within
- double getF()
- returns F value
- int getN(i)
- returns N of ith data set
- double getSSDev(i)
- returns Sum of Squared deviations of ith data set
- double getStdErr(i)
- returns Standard Error of ith data set
- double getProbF()
- returns the probability of getting the observed F or larger
