LinRegtTest LinRegtTest X,Y[,Freq[,Hypoth]] Computes the linear regression line fit of the data point pairs, where y(k) = a + b·x(k) and tests the null hypotheses H0: b = 0 against one of the following three alternatives: Hypoth > 0 is Ha: s1 > s2 Hypoth = 0 is Ha: s1 ƒ s2 (default) Hypoth < 0 is Ha: s1 < s2 A summary of results is stored in the stat.results variable. (See page 76.) Output variable stat.RegEqn stat.a, stat.b stat.df stat.s stat.t stat.PVal stat.r stat.r2 stat.SESlope stat.Resid Description regression equation: a + b·x Regression line fit offset and slope parameter estimates Degrees-of-freedom Fit error standard deviation for y - (a + b·x) T-Statistic for slope significance Probability the alternate hypothesis is false Linear regression correlation coefficient Coefficient of determination SE Slope = s/sqrt(sum(x-bar)2) residuals of linear fit @List( ) @List(List1) ⇒ list Returns a list containing the differences between consecutive elements in List1. Each element of List1 is subtracted from the next element of List1. The resulting list is always one element shorter than the original List1. list4mat() list4mat(List [, elementsPerRow]) ⇒ matrix Returns a matrix filled row-by-row with the elements from List. elementsPerRow, if included, specifies the number of elements per row. Default is the number of elements in List (one row). If List does not fill the resulting matrix, zeros are added. Catalog > Catalog > Catalog > 42 TI-Nspire™ Reference Guide
