多元統(tǒng)計分析實驗報告

./1.實驗目的：〔1掌握均值向量及協(xié)方差陣的檢驗方法?！?能夠用SPSS軟件或R軟件實現(xiàn)均值及協(xié)方差陣的檢驗,并正確理解輸出結果。2.實驗容均值向量檢驗和協(xié)方差陣檢驗3.實驗步驟〔1在進行比較分析之前,首先要對數(shù)據(jù)是否遵從多元正態(tài)分布進行檢驗。對數(shù)據(jù)進行以下操作"Analyze-descriptivestatistics-explore"。圖一圖二單擊plots,選擇正態(tài)分布檢驗,單擊continue,ok得出結果。圖三〔2多元正態(tài)分布有關均值與方差的檢驗,單擊"Analyze-generallinearmodel-multivariate",得到下圖。圖4Options打開,將省份導入displaymeansfor中,如圖5,continue繼續(xù),ok運行。圖54.實驗結果〔或心得體會TestsofNormalityKolmogorov-SmirnovaShapiro-WilkStatisticdfSig.StatisticdfSig.年末總戶數(shù)〔戶.11694.003.94294.000年末總人口〔萬人.40694.000.65994.000地方財政一般預算收入〔萬元.17494.000.84294.000行政區(qū)域土地面積.17794.000.83794.000其中：鄉(xiāng)村戶數(shù).14194.000.92494.000地方財政一般預算支出.25894.000.77794.000城鄉(xiāng)居民儲蓄存款余額.23094.000.60394.000規(guī)模以上工業(yè)企業(yè)個數(shù).16794.000.85494.000普通中學在校學生數(shù).33694.000.58894.000a.LillieforsSignificanceCorrection表一正態(tài)分布檢驗Kolmogorov-SmirnovaShapiro-WilkStatisticdfSig.StatisticdfSig.行政區(qū)域土地面積/平方萬公里.15976.000.85376.000鄉(xiāng)<鎮(zhèn)>個數(shù)/個.09876.066.96576.033村民委員會個數(shù)/個.06776.200*.96076.017年末總戶數(shù)/戶.08376.200*.95876.014其中：鄉(xiāng)村戶數(shù)/戶.11376.017.94976.004年末總人口/萬人.08976.200*.96376.026鄉(xiāng)村人口/萬人.13076.003.95676.010年末單位從業(yè)人員數(shù)/人.15376.000.87276.000鄉(xiāng)村從業(yè)人員數(shù)/人.10176.054.96276.023其中：農林牧漁業(yè)/人.09976.062.96076.018農業(yè)機械總動力/萬千瓦特.12176.007.86576.000本地年末用戶/戶.15176.000.84176.000第一產業(yè)增加值/萬元.13476.002.91076.000第二產業(yè)增加值/萬元.17476.000.76376.000地方財政一般預算收入/萬元.20776.000.76476.000地方財政一般預算支出/萬元.12276.007.93576.001城鄉(xiāng)居民儲蓄存款余額/萬元.19976.000.71476.000年末金融機構各項貸款余額/萬元.21476.000.64676.000糧食總產量/噸.20476.000.81776.000油料產量/噸.32576.000.50276.000肉類總產量/噸.15076.000.82676.000規(guī)模以上工業(yè)企業(yè)個數(shù)/個.20576.000.71976.000規(guī)模以上工業(yè)總產值<現(xiàn)價>/萬元.23076.000.72176.000城鎮(zhèn)固定資產投資完成額/萬元.18876.000.75576.000普通中學在校學生數(shù)/人.15076.000.88676.000小學在校學生數(shù)/人.09176.187.94876.004醫(yī)院、衛(wèi)生院床位數(shù)/床.15676.000.86576.000各種社會福利收養(yǎng)性單位數(shù)/個.11576.014.94476.002各種社會福利收養(yǎng)性單位床位數(shù)/床.17176.000.84576.000根據(jù)p值檢驗可以看到,這些變量都服從多元正態(tài)分布。表二多變量檢驗表EffectValueFHypothesisdfErrordfSig.Pillai'sTrace.96949.046a29.00046.000.000Wilks'Lambda.03149.046a29.00046.000.000Hotelling'sTrace30.92049.046a29.00046.000.000Roy'sLargestRoot30.92049.046a29.00046.000.000省份Pillai'sTrace1.6206.90158.00094.000.000Wilks'Lambda.0356.932a58.00092.000.000Hotelling'sTrace8.9696.95958.00090.000.000Roy'sLargestRoot5.5999.074b29.00047.000.000通過表二可以看出,無論從哪個統(tǒng)計變量來看,三個省的總體水平是有明顯差別的,從第一個檢驗可以得到的線性模型：。表明三個省份對指標的取值是有影響的,行業(yè)取之不同,通過擬合得到三個省值是有差異。如果x的系數(shù)是零,則無差異。表三EstimatesDependentVariable省份MeanStd.Error95%ConfidenceIntervalLowerBoundUpperBound行政區(qū)域土地面積/平方萬公里省4.800E3400.3644002.3735597.858省4.313E3416.7123482.3505142.984省3.149E3392.8802366.0213931.682鄉(xiāng)<鎮(zhèn)>個數(shù)/個省12.9231.05810.81515.031省14.4581.10112.26416.652省18.1481.03816.08020.217村民委員會個數(shù)/個省133.73114.612104.615162.846省223.20815.209192.904253.513省220.11114.339191.540248.682年末總戶數(shù)/戶省1.562E51.532E4125649.025186703.514省1.802E51.595E4148402.195211949.722省1.852E51.503E4155209.779215122.962其中：鄉(xiāng)村戶數(shù)/戶省8.102E41.104E459028.511103012.566省1.025E51.149E479646.430125426.486省1.373E51.083E4115692.519158854.370年末總人口/萬人省45.9234.81136.33855.509省53.7925.00743.81563.769省55.4814.72146.07564.888鄉(xiāng)村人口/萬人省30.9624.03322.92538.998省37.8754.19829.51046.240省44.7783.95836.89152.664年末單位從業(yè)人員數(shù)/人省2.187E42512.38216863.12426875.183省2.839E42614.97023179.80933600.691省2.231E42465.41717397.47527222.377鄉(xiāng)村從業(yè)人員數(shù)/人省1.664E51.980E4126987.118205877.190省1.867E52.060E4145658.930227770.320省2.353E51.943E4196591.986274007.347其中：農林牧漁業(yè)/人省1.153E51.306E489241.322141285.909省1.336E51.359E4106525.055160694.778省1.382E51.282E4112619.074163690.778農業(yè)機械總動力/萬千瓦特省49.0006.42436.20061.800省60.5006.68647.17873.822省50.9636.30438.40263.523本地年末用戶/戶省6.493E41.434E436353.24293515.989省9.895E41.493E469204.064128700.936省1.508E51.408E4122723.498178817.687第一產業(yè)增加值/萬元省2.498E54.002E4170005.803329508.043省3.235E54.166E4240464.652406479.848省3.457E53.928E4267458.501423979.128第二產業(yè)增加值/萬元省2.831E51.341E515830.732550370.422省6.908E51.396E5412612.850968979.400省1.255E61.316E5993045.2191517592.633地方財政一般預算收入/萬元省2.677E41.043E45991.70947553.060省4.765E41.086E426025.32969283.755省1.243E51.023E4103931.671144716.107地方財政一般預算支出/萬元省1.162E51.267E490989.000141461.077省1.897E51.318E4163441.831215974.835省2.004E51.243E4175586.519225115.110城鄉(xiāng)居民儲蓄存款余額/萬元省3.591E59.517E4169500.282548755.564省5.565E59.905E4359109.293753850.707省8.932E59.339E4707082.4091079248.183年末金融機構各項貸款余額/萬元省2.834E58.424E4115531.782451250.603省5.000E58.768E4325290.595674717.822省7.213E58.267E4556538.129885981.278糧食總產量/噸省1.047E61.237E5800676.3031293792.851省9.874E51.288E5730767.0951244019.072省4.225E51.214E5180539.883664438.487油料產量/噸省4.176E37802.098-11370.25019721.789省2.597E48120.6819793.10642154.727省2.518E47656.2529922.84540433.673肉類總產量/噸省5.631E41.722E422003.72390607.815省1.303E51.792E494608.048166013.452省1.175E51.689E483815.355151137.015規(guī)模以上工業(yè)企業(yè)個數(shù)/個省35.38527.625-19.66090.429省104.20828.75346.9161
