Body Mass Index Calculator is an easily calculated index of body fat for adults that uses only height and weight. The formula used in this Calculator is (Weight in Pounds / Height in Inches squared) x 703. The definitional formula is Weight in Kilograms /...
A standalone Macintosh program that calculates the chi-square statistic for 2x2 to 10x10 contingency tables. Also calculates the contingency coefficient, phi, and kappa statistics. The chi-square test is used to compare the distributions of two...
A standalone Macintosh program that performs a simple regression-based prediction of achievement for determination of a severe ability-achievement discrepancy. User enters an ability test score and the correlation between ability and achievement scores....
A stand alone Macintosh program that contains tables of eigenvalues produced by Monte Carlo simulations for determination of the number of factors to retain for rotation in factor analysis. It is, in essence, a large table of random eigenvalues generated...
Eigenvalues are point estimates and confidence intervals (CI) can be constructed around them (Zientek & Thompson, 2007). Confidence intervals convey important information about the precision of population parameter estimates. For eigenvalues, Larsen and...
This program calculates a modified Bonferroni method proposed by Holm (1979) that is more powerful than the traditional Bonferroni approach but maintains experimentwise error rate. Termed a sequentially-rejective Bonferroni method (Shaffer, 1995), it may...
Invariance calculates the coefficient of congruence (Rc), a chi-square goodness of fit test, and Cattell's Salient Variable Similarity Index. The Rc can be calculated from the matching factor loadings alone. The chi-square goodness of fit method also...
A standalone Macintosh program to compute the statistical significance of chi-square difference tests as typically used in comparisons of nested SEM models in EQS, LISREL, and Mplus SEM software as per Bryant and Satorra...
