eturns the aggregated student's t-test mean difference for a series of values iterated over the chart dimension(s).
See the TTest1w_t ([set_expression][ total [] weight, value) (page 793) function for
argument descriptions.
The same limitations with regard to nested aggregation as those listed under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function apply. This function
supports the total qualifier in the same manner as described under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function.
Examples:
ttest1w_dif( Weight, Value )
TTest1w_sterr ([set_expression][ total [] weight,
value)
returns the aggregated student's t-test standard error of the mean difference for a series of values iterated over
the chart dimension(s). See the TTest1w_t ([set_expression][ total [] weight, value) (page 793)
function for argument descriptions.
The same limitations with regard to nested aggregation as those listed under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function apply. This function
supports the total qualifier in the same manner as described under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function.
Example:
ttest1w_sterr( Weight, Value )
TTest1w_conf ([set_expression][ total [] weight, value
[, sig = 0.025 ])
returns the aggregated t value for a series of values iterated over the chart dimension(s). The two-tailed level
of significance can be specified in sig. If omitted sig will be set to 0.025, resulting in a 95% confidence interval.
See the TTest1w_t ([set_expression][ total [] weight, value) (page 793) function for descriptions
of the other arguments.
The same limitations with regard to nested aggregation as those listed under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function apply. This function
supports the total qualifier in the same manner as described under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function.
Examples:
ttest1w_conf( Weight, Value )
ttest1w_conf( Weight, Value, 0.005 )
TTest1w_lower ([set_expression][ total [] weight, value
[, sig = 0.025 ])
returns the aggregated value for the lower end of the confidence interval for a series of values iterated over
the chart dimension(s). See the TTest1w_t ([set_expression][ total [] weight, value) (page 793)
and TTest1w_conf functions for argument descriptions.
The same limitations with regard to nested aggregation as those listed under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function apply. This function
supports the total qualifier in the same manner as described under the chi2test_p ([set_expression][
total [] col, row, observed_value [, expected_value]) (page 785) function.
