StatAssist displays graphs and related properties of more than 40 probability distributions. This application will save you time and prevent calculation errors if your work or study involves the use of continuous or discrete distributions. It allows to quickly select a distribution of interest, specify parameter values, and view the graphs - probability density (PDF), cumulative probability (CDF), survival, hazard, and cumulative hazard. You can easily export the results to various formats, or print them.
With StatAssist, you don't need complex statistical tables - it calculates moments, quantiles, and tail probabilities as you modify distribution parameters. In addition, it includes an efficient random number generator, a visual distribution gallery, and a comprehensive on-line documentation.
Supported distribution properties: min, max, mode, mean, variance, standard deviation, coef. of variation, skewness, and kurtosis.
Supported distributions: Bernoulli, Beta, Binomial, Cauchy (Lorentz), C ...
Server performance comes down to one thing: How fast can the drives deliver data? No matter how much you spend on multiple processors and additional memory, that investment is wasted if the hard drive can't deliver data in a timely manner. Even high-end RAID controllers and Storage Area Networks can't overcome the effects of fragmentation: If the operating system breaks the file up, then your disk array will store it accordingly. The only way to keep files contiguous so they can be accessed quickly is with routine defragmentation.
This problem cannot be solved manually; after all, what organization can afford the hours of downtime it would take to defragment each server daily, let alone enterprise-level servers? Infrequent defragmentation is no better: Fragmentation builds exponentially, and every day sees a decrease in performance and an increase in the likelihood of fragmentation-related downtime. Automatic defragmentation is the only solution
CurvFit (tm) is a curve fitting program 4 Windows 95/98. Lorentzian, Sine, Exponential and Power series are
available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple
peaked/valleys data. CurvFit is an example of Fortran Calculus programming... ie. minutes to solve, days or years to
understand solution and what it implies (e.g. wrong model, sampling rate error). See comments in EX-*.
This aims to supply a Borland Delphi translation of Alan Miller's Random Module for FORTRAN-90. This translation has been done with Dr Miller's approval and is being made FREELY available to all Delphi Developers, though we do ask the Alan Miller and ESB Consultancy be given due credit. Random Number Generators include Normal, Poisson, Gamma, Chi-Squared, Exponential, Beta, Weibull, Binomial and more. Includes full Delphi Source and Demo.
The Multiple Regression Analysis and Forecasting model provides a solid basis for identifying value drivers and forecasting business plan data. While it utilises a range of commonly employed statistical measures to test the validity of the analysis, results are summarized in text for ease of use. Once relationships have been identified, forecasting can be accomplished based on a range of available methodologies. The intuitive step-by-step usage flow enables you to develop strong forecasts for your projects in a timely manner. The key features of the Multiple Regression Analysis and Forecasting model include: Ease and flexibility of input, with embedded help prompts; User-friendly results display for the 'Non-statistician'; Multiple and Individual Regression of independent variables; Tests for statistical significance, auto-correlation, and multi-colinearity; and Quick forecasting process with options to employ 3rd polynomial, 2nd polynomial, exponential or linear trend lines on independent variabl ...
