The app calculates dose rates etc. assuming a point source in vacuum and linear attenuation in shielding materials. Isotopes and shielding materials can be added, deleted or modified.

The predefined gamma rate constants and attenuation coefficients were found on the web. I do not guarantee correct predefined values.

From Summary Data – supply number of subjects, mean and standard deviation
From Detail Data – supply data within a group and keep adding groups
From Data File – supply tab delimited file.

Beta Function:

Beta Function Calculator
Incomplete Beta Function Calculator
Regularized Incomplete Beta Function Calculator

Scientific Calculator (Infix notation):

18 Basic Arithmetic Operations
Ability to specify and perform fractions
5 Probability Operations
4 Memory Operations
13 Trigonometry operations
5 Statistics functions + data repeat
Specify significance and precision
Autometic precedence and ability parenthesis

Covariance & Correlation:

Covariance and Correlation by entering data. Data sets need to appear column wise. When a row is added, the data points for all the groups in the same position are added.
Covariance and Correlation from file
Covariance from correlation
Correlation from covariance
Significance of correlation

Effect Size:

Effect Size – Hierarchical Multiple Regression
Effect Size – Multiple Regression
Effect size Student’s t-Test: Calculates the (two-tailed) effect size for Student’s t-test (Cohen’s d), given the mean and standard deviation for two independent samples of equal size.

Error Function:

Computes the value of the error function (a.k.a the Gauss error function) evaluated at a value of x. The value returned will be the error function evaluated along the integral from zero to x.
Computes value of the complementary error function. Error function evaluated along the integral from x to positive infinity.

Gamma Function:

Gamma Function
Incomplete Gamma Function
Regularized Incomplete Gamma Function
