Initial sample dosage N1, adjustment sample dosage N2 and qualification rate r；
Result-generation module: the calculated result for reading data and the data processing module according to the data historian is raw
At report or curve；
The report that the result-generation module generates includes that each region levelling sample size shows report daily and each region is closed daily
Lattice rate report；
The curve that the result-generation module generates includes that specified region levelling sample size shows curve and specified region qualification rate
Show curve, wherein qualification rate shows that curve shows that qualification rate examines lower limit straight line simultaneously.
The data historian is read once according to daily.
The initial sample dosage N1 calculation formula of two points of qualification rate peasant households to be extracted number is as follows:
Wherein, R is the error allowed, σ2For population variance, Z is standardized normal distribution amount.
The adjustment sample dosage N2 calculation formula of two points of qualification rate peasant households to be extracted number is as follows:
。
Two points of sampling observation personnel are differentiated with the peasant household's photo for adjusting sample dosage N2 quantity, obtain corresponding acceptance number K,
The two lattices rate calculation formula is as follows:
r=K/N2。
For residents in rural community receive fortune two points of qualification rates appraisal system examining method the following steps are included:
S1. it from initial time, reads total size M and qualification rate examines lower limit；
S2. according to the data read in S1 step, initial sample dosage N1, adjustment sample dosage are calculated using data processing module
N2；
S3. according to the adjustment sample dosage N2 calculated in S2 step, two points of sampling observation personnel are sentenced with peasant household's photo of N2 quantity
Not, corresponding acceptance number K is obtained；
S4. the acceptance number K according to obtained in adjustment sample dosage N2 and the S3 step calculated in S2 step, utilizes data processing mould
Block calculates two points of qualification rate r；
S5. according to calculating in the data and step S2 or S4 read in S1 step as a result, generating report using result-generation module
Or curve.
Compared with prior art, the present invention having the following advantages that and effect: every by the statistics each region of each receipts fortune person
It receipts fortune rubbish sum calculates two points of qualification rate peasant households to be extracted with simple random sampling formula as sample total size
Several initial sample dosages adjusts formula by initial sample size according to total size and initial sample dosage and calculates adjustment initially
Sample dosage, two points of sampling observation personnel are differentiated with the peasant household's photo for adjusting initial sample dosage, obtain corresponding acceptance number, most
Two points of qualification rates are obtained with two lattice rate calculation formula afterwards.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
The present invention provides a kind of appraisal system of residents in rural community receipts fortune qualification rate, comprising:
Data historian: for reading total size M, acceptance number K and qualification rate examination lower limit, total size M is each receipts fortune
The daily receipts fortune rubbish sum in each region of member, acceptance number K are the corresponding qualified number of pictures of adjustment sample dosage；
Data processing module: the data for being read according to the data historian calculate two points of qualification rate peasant households to be extracted number
Initial sample dosage N1, adjustment sample dosage N2 and qualification rate r；
Result-generation module: the calculated result for reading data and the data processing module according to the data historian is raw
At report or curve；
The report that result-generation module generates includes that daily each region levelling sample size shows report and daily each region qualification rate
Report；
The curve that result-generation module generates includes that specified region levelling sample size shows that curve and specified region qualification rate are shown
Curve, wherein qualification rate shows that curve shows that qualification rate examines lower limit straight line simultaneously.Data historian of the present invention is read according to daily
It takes primary.
The initial sample dosage N1 calculation formula of two points of qualification rate peasant households to be extracted number is as follows:
Wherein, R is the error allowed, σ2For population variance, Z is standardized normal distribution amount.
According to above formula, confidence interval 1- α=95% is generally taken, Z=1.96 can be obtained by looking into gaussian distribution table；
Population variance σ2, when studying index and taking two values, i.e. when P and 1-P, P be the qualified probability of sampling, and 1-P is samples not
Qualified probability, therefore σ2=MP(1-P)；
Investigate P(1-P) maximum value, due to 0≤P≤1；Then the maximum value of the formula is 0.25, therefore σ2=0.25×M；
In conclusion the initial sample dosage N1 calculation formula of two points of qualification rate peasant households to be extracted number is simplified as:
The adjustment sample dosage N2 calculation formula of two points of qualification rate peasant households to be extracted number is as follows:
Two points of sampling observation personnel are differentiated with the peasant household's photo for adjusting sample dosage N2 quantity, obtain corresponding acceptance number K；
The two lattices rate calculation formula is as follows:
r=K/N2。
The present invention for residents in rural community receive fortune two points of qualification rates appraisal system examining method the following steps are included:
S1. it from initial time, reads total size M and qualification rate examines lower limit；S2. according to the data read in S1 step,
Initial sample dosage N1, adjustment sample dosage N2 are calculated using data processing module；S3. according to the adjustment sample calculated in S2 step
This dosage N2, two points of sampling observation personnel are differentiated with peasant household's photo of N2 quantity, obtain corresponding acceptance number K；S4. it is walked according to S2
Acceptance number K obtained in adjustment sample dosage N2 and the S3 step calculated in rapid calculates two division lattice using data processing module
Rate r；S5. according to calculating in the data and step S2 or S4 read in S1 step as a result, generating report using result-generation module
Or curve.
