The unit stratum variable. One dimensional object convertible to one-column |
PSU |
Primary sampling unit variable. One dimensional object convertible to one-column |

The vector of periods from variable |
in_sample |
Sample variable. One dimensional object convertible to one-column |
in_frame |
Frame variable. One dimensional object convertible to one-column |
confidence |
optional; either a positive value for confidence interval. This variable by default is 0.95. |
percentratio |
Positive numeric value. All linearized variables are multiplied with |
