RPN CAlcSeries Statistics for 2 Variables - This program calculates 2 variables statistics (grouped or ungrouped), linear regression and factorial functions, as described below:
· X mean
· X weighted mean
· Y mean
· X standard deviation (Sx)
· Y standard deviation (Sy)
· covariance (Sxy)
· X coefficient of variation (Vx)
· Y coefficient of variation (Vy)
· correlation coefficient (Vxy)
· sums of data points (Sum Xi, Sum Yi)
· sum of multiplication of data points (Sum XiYi)
· sums of squares of data points (Sum Xi2, Sum Yi2)
· data points could be derived from a set of ungrouped data points {(Xi, Yi), i=1, 2, ..., n}, or grouped data points {(Xi, Yi, fi), i=1, 2, ..., n}, where fi denotes the frequency of repetition of (Xi, Yi).
· calculation could be done, based either on 'n' or 'n-1' sample number of elements
· linear regression
· X linear estimation
· Y linear estimation
· correlation coefficient (r) for linear regression
· factorial (extended range) - factorial results could be greater as E 999, meaning you can calculate factorials for numbers up to 450
· permutation (extended range)
· combination (extended range)
· on-line User Guide
· Hi-Resolution (320x480) support
· User-friendly interface
· RPN stack display
· 90 independent storage registers
· Upgrades / updates are life-time free of charge
