Chi-Squared GOF

Description: Returns the chi-squared goodness-of-fit results for the selected mode type. This function applies only when you use the Crow Extended model with either grouped times-to-failure or Discrete Mixed data types.

Field Format: [CHIGOF_M(Source Number)(Value_Index;Mode_Type;Signif_Level)]

Source Number is the associated data source number.

Value_Index is a numerical value that allows you to specify which result to display:
- To show whether the test passed or failed = 0.
- To return the critical value = 1.
- To return the test value = 2.

Mode_Type allows you to select the mode classification. It is shown in the function as a numerical value that indicates the selected mode: BC Modes = 1; BD Modes = 2; All Modes = 3.

Signif_Level is the significance level for the results.

Remarks:

The Source Number must be either 1,2,3 or 4.

If the critical value is less than the test value, then the chi-squared test passes.

Example:

[CHIGOF_M(1)(1;3;5)]

Returns:

2.794492824

Note that this value will vary depending on the source data set.
