This function applies to one-sample student's t-tests where the input data series is given in weighted two-column format.
If the function is used in the data load script, the values are iterated over a number of records as defined by a group by clause.
If the function is used in a chart expression, the values are iterated over the chart dimensions.
TTest1w_lower (weight, value [, sig ])
Return data type: numeric
||The samples to be evaluated. If a field name for the sample values is not provided in the load script, the field will automatically be named
||Each value in value can be counted one or more times according to a corresponding weight value in weight.|
|sig||The two-tailed level of significance can be specified in sig. If omitted, sig is set to 0.025, resulting in a 95% confidence interval.|
