Statistics: Mean, median, standard deviation and variance of a sample and the corresponding histogram are calculated.
Regression: The regression curve to fit a sample of points is calculated. Supported are proportional regression, linear regression, geometrical regression, exponential regression, logarithmic regression and polynom regression
Logistische Regression (Neu in Version 9.0): The program determines for a series of measurements a curve fit to the logistic function
with the parameters a₁ = ƒ(0)·S , a₂ = ƒ(0) , a₃ = S - ƒ(0) , a₄ = -k·S and the saturation limit S .
Combinatorial Analysis: The number of arrangements and combinations of k out of n elements, with or without repetitions are calculated.
Binomial Distribution: For a b(k;n;p) distributed random variable X with fixed n and p you receive a histogram of the probabilities P( X = k ), a table of their values from k_min to k_max and the probability P(k_min≤X≤k_max).
Hyper Geometric Distribution: For a h(k,n,m,r) distributed random variable X with fixed n, m and r you receive a histogram of the probabilities P( X = k ), a table of their values from k_min to k_max and the probability P(k_min≤X≤k_max).
Normal Distribution: For a normal distributed random variable X with given mean μ and variance σ you receive the density function and the distribution function.
