Univariate Statistical Distributions | |
Random Number Generator - Normal Distribution | Generates random numbers for the Normal distribution. |
Maximum-likelihood Fitting - Normal Distribution | Maximum-likelihood Fitting of the Normal Distribution for any univariate data series. This includes the Normal QQ Plot and Histogram with the curve of the fitted normal distribution. |
CDF Normal | computes the cumulative probability of the Normal Distribution for a given value (quantile), mean, and standard deviation |
Random Number Generator - Log-Normal Distribution | Generates random numbers for the Log-Normal distribution and estimates the parameters. It is illustrated that the estimated mean and standard deviation is normally distributed. |
Maximum-likelihood Fitting - Beta Distribution | computes the shape and rate parameter of the Beta distribution and the PPCC Contour Plot |
Maximum-likelihood Fitting - Cauchy Distribution | computes the location and scale parameter of the Cauchy distribution |
Maximum-likelihood Fitting - Exponential Distribution | computes the rate parameter of the Exponential distribution |
Maximum-likelihood Fitting - Gamma Distribution | computes the shape and rate parameter of the Gamma distribution and the PPCC Plot |
Maximum-likelihood Fitting - Lognormal Distribution | computes the meanlog and sdlog parameter of the Lognormal distribution and the PPCC Plot |
Maximum-likelihood Fitting - Logistic Distribution | computes the location and scale parameter of the Logistic distribution |
Maximum-likelihood Fitting - Negative Binomial Distribution | computes the size and mu parameter of the Negative Binomial distribution |
Maximum-likelihood Fitting - Poisson Distribution | computes the lambda parameter of the Poisson distribution |
Maximum-likelihood Fitting - Weibull Distribution | computes the shape and scale parameter of the Weibull distribution and the PPCC Plot |
Tukey lambda PPCC Plot | computes the Tukey lambda PPCC Plot |
Box-Cox Normality Plot | computes the Box-Cox Normality Plot |
Area under Normal Density | computes the area under the normal density for a given lower and upper value, mean, and standard deviation. |
Area under Binomial Density | computes the area under the Binomial density. |
Skewness/Kurtosis Test | D'Agostino skewness test, Anscombe-Glynn kurtosis test, Jarque-Bera Normality Test (against normality). |
Skewness-Kurtosis Plot | Skewness-Kurtosis plot as proposed by Cullen and Frey (1999). |
