of expected counts. Returns a list containing the chi-square
statistic value, the probability, and the degrees of freedom.

Chi2GOF(List1, List2, Value)

Example:

Chi2GOF({10,10,12,15,10,6},{.24,.2,.16,.14,.1
3,.13},0) returns {10.1799..., 0.07029..., 5}

Chi2TwoWay

Chi-square two-way test. Given a matrix of count data, returns
a list containing the chi-square statistic value, the probability,
and the degrees of freedom.

Chi2TwoWay(Matrix)

Example:

Chi2TwoWay([[30,35,30],[11,2,19],[43,35,35]])

returns {14.4302..., 0.0060..., 4}

LinRegrTConf-

Slope

The linear regression confidence interval for the slope. Given
a list of explanatory variable data (X), a list of response
variable data (Y), and a confidence level, returns a list
containing the following values in the order shown:

C: the given confidence level

Critical T: the value of t associated with the given
confidence level

DF: the degrees of freedom

β

1

: the slope of the linear regression equation

serrSlope: the standard error of the slope

Lower: the lower bound of the confidence interval for the
slope

Upper: the upper bound of the confidence interval for the
slope

LinRegrTConfSlope(List1, List2, C-value)

Example:

LinRegrTConfSlope({1,2,3,4},{3,2,0,-2},0.95)

returns {0.95, 4.302..., 2, -1.7, 0.1732...,
-2.445..., -0.954...}
