Bounds on Time Given MTBF

Description: Returns the 1-sided bound at the specified confidence level on the time corresponding to the specified cumulative/instantaneous MTBF.

Field Format: [BOUNDSTIMEMTBF(Source Number)(MTBF;Type;Conf_Level)]

Source Number is the associated data source number.

MTBF is the value of the MTBF at which the time is calculated.
Type is an index number (0 to 1) that returns the following information:
- 0 = returns the instantaneous MTBF
- 1 = returns the cumulative MTBF

Conf_Level is the percentage (entered as a decimal value) for the confidence bounds. It is an optional value and, if specified, must be greater than 0 and less than 1.

Remarks:

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

Example:

[BOUNDSTIMEMTBF(1)(250;0;0.9)]

Returns:

2744.245089

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