Given values of test statistics (and the appropriate additional information) the value of the noncentral values can be obtained. Likewise, given noncentral values (and the appropriate additional information) the value of the test statistic can be obtained.

Lambda2Rsquare(Lambda = NULL, N = NULL)
Rsquare2Lambda(R2 = NULL, N = NULL)
squared multiple correlation coefficient (population or observed)
degrees of freedom for the numerator of the F-distribution
degrees of freedom for the denominator of the F-distribution
number of predictor variables for R2
sample size
The obtained F value from a test of significance for the squared multiple correlation coefficient
The noncentral parameter from an F-distribution
Returns the converted value from the specified function.
These functions are especially helpful in the search for confidence intervals for noncentral parameters, as they convert to and from related quantities.
