Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as figure 1 As shown, in the embodiment of the present invention, a method for sampling survey is proposed, the method includes:

[0034] Step S101, select the required sampling sample range, obtain multiple business types of the sampling sample and the number of samples corresponding to each business type;

[0035] Such as figure 2 As shown, the sample range includes the sampling time, the business type of the sample, and the sampling survey department. The business personnel can select the required sample in the sample range (such as figure 2 "√" selected in the middle), to get m...

Abstract

The embodiment of the invention discloses a method for a sample survey. The method includes the steps of selecting the range of samples and obtaining the service types of the samples and the sample number of the service types; according to the service types and the sample number, setting sampling survey cost and a sample distribution method, and estimating the total number of the samples and the sample quantity of the service types; selecting one service type, obtaining the sample quantity of the service type, and setting a sampling method to obtain the sample extraction quantity of the service; according to the sample distribution method and the sampling method, determining an overall calculation algorithm, and calculating an overall estimation mean value and an estimation variance of the sample quantity of the service according to the overall calculation algorithm, the sample quantity of the service and the sample extraction quantity of the service. The embodiment of the invention further discloses a system for the sample survey. According to the method and the system, the problems that in the prior art, the requirements for quality of professionals are high, and a sampling method is complex and low in efficiency, operated manually and not suitable for periodical sampling surveys are solved.

Description

technical field [0001] The invention relates to the technical field of power system measurement, in particular to a sampling survey method and system. Background technique [0002] Sampling survey has been widely used in social economy, science and technology, nature and other fields, and it is one of the important means for researchers to obtain statistical data. Researchers usually use the sampling module of general-purpose statistical software to conduct sample survey analysis. The traditional method of operation is to first import business data into statistical software, then conduct sampling through the sampling module of general statistical software, and finally import the survey result data into statistical software for statistical inference. [0003] This method has the following disadvantages: (1) This method requires high statistical knowledge and software programming knowledge of specific operators, and a code error in any link will cause inference errors; (2) Th...
