CalEst is a statistics package which also includes probability functions as well as tutorials to enhance the learning of Statistical and Probability. It was developed at CONTECK by researchers Jorge Dominguez and Axel Dominguez.

Statistics functions

CalEst includes several Statistical functions, such as: Anova, Regression_analysis, Inference (Statistical hypothesis testing), Descriptive_statistics (Histogram, Pie Chart, Stemplot among other graphics as well as Summary statistics like Arithmetic_mean, Median, Mode and more).

Probability distributions

CalEst incorporates 16 Probability_Distribution. The user can use the graphic representation of these distributions to manipulate the thresholds and the parameters. The graphic automatically adjusts itself and provides several information (e.g., area). CalEst also provides a calculator-style interface. In both cases, the user can use the density or accumulative distribution.

The probability distributions included in the latest version of CalEst are:Discrete
*Bernoulli_distribution
*Binomial_distribution
*Poisson_distribution
*Uniform_distribution_%28discrete%29Continuous
*Beta_distribution
*Chi-square_distribution
*Exponential_distribution
*Extreme_value_distribution
*F-distribution
*Gamma_distribution
*Normal_distribution
*Logistic_distribution
*Log-normal_distribution
*Student%27s_t-distribution
*Uniform_distribution_%28continuous%29
*Weibull_distribution
