Testimonials

(G.W.) "Worth every penny!!! Two years ago I purchased the 5 app special and I'm still discovering new capabilities on a regular basis. A must have for every student and professional. I am still amazed by how much time and thought the designers invested in these programs. I can honestly say they did a great job and they stand by their product. Customer service/technical help is impressive too!! Thanks Guys."

Description

- 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.
