Follow @timathapps  Solve Actuarial Math problems instantly...Step by Step Joint, Marginal and Conditional Probabilities for both Continuous and Discrete distributions. Find cdf given pdf and vice versa. Forecasting: Forcast and Project into the future using tools such as 8 Regressions Methods, Smoothing (Simple Exponential or using Seeds) or Simple Moving Averages.    Find Step by Step solutions for most Statistics topics: Step by Step Confidence Intervals for mean, proportion, 2 means, 2 proportions, variance, slope, etc. Compute Sample Sizes for Confidence Intervals. Step by Step Tests of Significance (Z-Tests, T-Tests, ChiSquare Goodness of Fit and Independence tests, 2-sample T tests, 2 proportion Z tests, for Variance,  etc) Read about how Confidence Intervals behave. Read about how Significant Tests: Type 1 Error, Type 2 Error, Power of a Test. Much easier handling than other Statistics packages: Choose to enter Data or Statistic values. Select Significant/Confidence Levels easily.  Distributions: plot them, shade them where desired, compute probabilities, etc. Includes Binomial, Negative Binomial, Geometric, Normal, Student-t, Exponential, Poisson, Uniform, Sampling, Multinomial, Hypergeometric, F-, Chi-Square and more Distributions.  Newly added: Double Exponential, Cauchy and Bivariate Normal Distributions. Probability Checker for independent events, disjoint events. Also solves P(A or B)=P(A)+P(B)-P(A and B) for the unknown.   Regressions: Linear , Quadratic, Cubic, Quartic, Sinusoidal, Logarithmic, Exponential, Power, MedMed Study Residuals and plot them Step by Step Derive the Coefficients for a Linear Regression Line, the Coefficient of Determination and the Correlation Coefficient. Read Theorems such as Central Limit Theorem, Random Variables, about Confidence Intervals and Tests, etc Also: Z-score Solver, Random Number Generator, etc 1 or 2 variable stats on mean, mode, median, standard deviation, variance, range, harmonic and geometric mean  Plots: BoxPlots, x-y Plots, Scatter Plots, Histograms, Modified Box Plot View a simulation of the Law of Large Numbers, Read about Simpson Paradox. Compute Marginal and Conditional Probabilities. Read About Surveys, Samples, Population, Parameter, Statistics, Observational Studies vs Experiments. Random Variables: Compute Variance, Expected Value and Standard Deviation. Additional Modules on: Probability, Combinatorics, Algebra, Equation Solver   Multiple Regression Analysis Step by Step incl. Statistical Tests (optional table displays as in other software packages), Confidence Intervals and Prediction Intervals. Control Charts Step by Step Power-, Beta- , Type 2 Error Analysis for Z Tests for Means and Proportions.  Non-Parametric Tests for 1 sample: Sign Test, Rank Sum Test Normal Probability Plot with Quantiles Weibull, Gamma and Beta Distributions.
