## Properties

### Object Name:

**Name of the object in BI****Authorized names are made using the letters of the alphabet and numbers, except the first letter. Use of “_” and space is not allowed.****It is not allowed to use the names in the Pane Variable**

**Current Value:**

**Current Value:****It is a float value which can be used as a start point in an analysis****When it changes, the PDF and CDF according to this value can be seen in rows 16 and 17, respectively**.

**q:**

**q:****It is a float value between 0 and 1 that represents the CDF of the probabilistic distribution and the inverse CDF for this value that it is showed in row 18**

**Distribution Type:**

**Distribution Type:****Probability distribution of the random variable****Probability distribution properties are defined by the parameters inside the parentheses****A probability distribution object may have six input parameters, the number of which is equal to the number of parameters in parentheses****If a probabilistic distribution object has two parameters in parentheses, only parameters 1 and 2 will be active for it and other parameters will be ignored****For example, in the normal distribution, parameter 1 is the mean and parameter 2 is the standard deviation**

**Parameter 1:**

**Parameter 1:****The first parameter of probability distribution that can be seen in the parentheses**

**Parameter 2:**

**Parameter 2:****The second parameter of probability distribution that can be seen in the parentheses**

**Parameter 3:**

**Parameter 3:****The first parameter of probability distribution that can be seen in the parentheses**

**Parameter 4:**

**Parameter 4:****The third parameter of probability distribution that can be seen in the parentheses**

**Parameter 5:**

**Parameter 5:****The fourth parameter of probability distribution that can be seen in the parentheses**

**Parameter 6:**

**Parameter 6:****The fifth parameter of probability distribution that can be seen in the parentheses**

**Coefficient Of Variation:**

**Coefficient Of Variation:****Coefficient of variation of the probability distribution**

**Mean:**

**Mean:****Mean of the probability distribution**

**Standard Deviation:**

**Standard Deviation:****Standard deviation of the probability distribution**

**Skew:**

**Skew:****Skewness of the probability distribution**

**Kurtosis:**

**Kurtosis:****Kurtosis of the probability distribution**

**PDF:**

**PDF:****PDF value of the current value applied in row 2**
