kixi.stats.test — kixi/stats 0.5.3

chi-squared-test clj/s

(chi-squared-test table)

Calculates the X^2 test of independence for a given contingency table. See kixi.stats.core/cross-tabulate

p-value clj/s

significant? clj/s

simple-t-test clj/s

(simple-t-test {:keys [mu sd]} {:keys [mean n]})

Calculates the t-test of statistical significance for a sample mean. mu: the population mean sd: the population standard deviation mean: the sample mean n: the sample size See also: kixi.stats.core/simple-t-test

simple-z-test clj/s

(simple-z-test {:keys [mu sd]} {:keys [mean n]})

Calculates the z-test of statistical significance for a sample mean. mu: the population mean sd: the population standard deviation mean: the sample mean n: the sample size See also: kixi.stats.core/simple-z-test

t-test clj/s

(t-test {mean-a :mean sd-a :sd n-a :n} {mean-b :mean sd-b :sd n-b :n})

Calculates Welch's unequal variances t-test of statistical significance. Requires the mean, sd and sample size (n) of both samples. See also: kixi.stats.core/t-test

test-result clj/s

(test-result statistic distribution)

(test-result statistic distribution alternate)

TestResult clj/s

z-test clj/s

(z-test {mean-x :mean sd-x :sd n-x :n} {mean-y :mean sd-y :sd n-y :n})

Calculates the z-test of statistical significance between two sample means. Requires the mean, sd and sample size (n) of both samples. See also: kixi.stats.core/z-test
