趨均數回歸 的英文怎麼說
中文拼音 [qūjūnshǔhuíguī]
趨均數回歸
英文
regression to the mean-
There was double - logarithmic linear correlation significantly between specific weight metabolic rate and temperature in each of weight groups. temperature exponent ( b ) in the regression equation increased with weight increasing. the covariance analysis showed that the difference between the every two temperature exponents in the equations was significant
（ 2 ）特定體重代謝率隨溫度的上升而上升，各體重組的代謝率與溫度之間均呈顯著的雙對數直線相關；溫度指數（ b ）隨體重的增加呈現上升的趨勢，協方差分析表明，回歸方程的溫度指數（ b ）間差異顯著。Seasonal dynamic model is introduced to analyze and evaluate tianjin raw water quality of luanhe river during 10 years for the first time, and so does for huanghe river during 4 years. based on these historical data, some long - term trend function of water quality items is got, by which seasonal fluctuation rate ( s c ) and seasonal dynamic trend of water quality items are computed. for the first time, clustering analysis is introduced to divide tianjin raw water into different levels
首次採用季節變動模型對天津市灤河水源10年的水質情況和黃河水源4年的水質情況進行了分析評價，得出各個水質指標的長期趨勢項回歸方程，根據趨勢模型和各水質指標的歷史數據求出季節比sc ，在各個指標的季節平均值和對應的季節比（ sc ）的基礎上，得到了各個水質指標的季節變化趨勢值。Adopting the actual county - grade database of land use firstly founded in china, combining with the comprehensive influential factors of land use change, using the correlative statistic software and the mathematic analytical methods ( principal component analysis, gray relating analysis, multivariate time series markov chain analysis, multivariate regression analysis, gm ( 1, 1 ) gray model, gray series gm ( 1, n ) model methods etc ), this paper analyses the dynamic change of land use and driving force in jiang ' an county qualitatively and quantitatively. the results indicate : 1 the land resource per capita and the area of single - land - use type in jiang ' an county are not prior to other places in yibing city or sichuan province. however, the terrain is dominant in choosing the way of land use
本文採用全國首批建立的「縣級土地利用現狀數據庫」的基礎數據，結合影響土地利用變化的經濟、社會、環境等綜合因素，採用相關分析軟體（ dps 、 spss ）和數學分析方法（主成分分析、灰色關聯度分析、多元回歸分析、多元時空序列馬爾柯夫鏈分析、 gm （ 1 ， 1 ）預測模型分析、灰色序列gm （ 1 ， n ）模型分析等方法） ，對江安縣土地利用變化及其驅動力進行定性、定量研究，研究結果表明： 1江安縣人均總的土地資源數量和單一土地利用類型的數量在宜賓或四川省區域內均無優勢；地形對土地利用方式的選擇起著主導作用；土地利用變化的總趨勢是：耕地、林地、交通用地和水域面積不斷減少，居民點及工礦用地和未利用地面積不斷增加；景觀多樣性指數呈現「 」趨勢。Hereafter being the forecasting to the old age population coefficient, this text has been applied two kinds of regression model, namely univariate linear model and logarithmic model, and thought over three kinds of economic speed of development ( high, middle, low ) in the logarithmic model to forecast the old age population coefficient respectively. finally, by analyzing the forecasted value and the inertia law of population development, the paper points out the lengthening of the population equally expected life span will push forward the aging of population step by step to the advanced age development ; the development trend of the population aging continues to be clear, and just appears a stage characteristic ; furthermore, the population aging speed in rural area will be faster than in the city
此後是對老年人口系數的預測，本文應用了兩種回歸模型，即一元線性回歸模型和對數擬合模型，並在對數擬合模型中考慮了經濟發展速度的高、中、低三種方案，對老年人口系數分別進行預測；最後在分析預測值和人口發展慣性規律基礎上對山東省未來人口老齡化發展趨勢作了較深入分析，指出人口平均預期壽命的不斷延長，將逐步推動人口老齡化向高齡化發展；人口老齡化繼續發展趨勢明顯，且呈現出階段性特徵；農村人口老齡化速度將快于城市。分享友人
