# Topics of the menu Stochastics

- 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*a*ƒ_{1}=*(0)·S*,*a*ƒ_{2}=*(0)*,*a*ƒ_{3}= S -*(0)*,*a*and the saturation limit_{4}= -k·S*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.
