该模型显示,在标准化的感觉温度下,自行车的数量将增加5.35倍。然而,这个数字需要仔细解释。数据中感觉温度的范围从4oC到45oC。此外,一个单位的时间增加意味着温度升高50度。一方面,这种感觉温度的急剧上升是极不可能的,极端的温度非常高,非常低,这将会阻碍道路上自行车的数量。因此,如果感觉温度升高1oC,那么在时间上的有效变化将是0.02,而相应的自行车数量的预期变化将会以5.350.02的分数增加,等于1.03。因此,在感觉温度的单位增加时,可以预计数字自行车增加了3%,ceteris paribus。

其他的变量需要同样的解释。对于一个单位的湿度增加,标准化湿度的有效增加是0.01,这就意味着自行车的数量下降到初始数量的0.99,所有的东西都保持不变。换句话说,一个单位在湿度水平上的增加,公路自行车数量的预期下降是0.67%。风速的单位增加等于归一化风速大小的0.015减小。相应的,自行车的有效数量是初始数量的0.985倍,ceteris paribus。因此,由于一个单位的风速增加,商业自行车的预期百分比下降是1.5%。

The model shows that for a unit increase in the standardized feeling temperature, the number of bikes will increase 5.35 times. However, this number needs to be interpreted carefully. The range of feeling temperature in the data is from 4oC to 45oC. Furthermore, a unit increase in atemp implies a 50oC increase in feeling temperature. While for one thing, such a stark increase in feeling temperature is highly unlikely, extreme temperatures both very high and very low will deter the number of bikes on road. Thus, if the feeling temperature was to increase by 1oC, the effective change in atemp will be 0.02 and the corresponding expected change in the number of bikes will increase by a fraction of 5.350.02 which is equal to 1.03. Thus, for a unit increase in feeling temperature, a 3% increase in number bikes can be expected, ceteris paribus.

The other variables need to be interpreted similarly. For a unit increase in humidity, the effective increase in normalized humidity is 0.01 which translates into a decline of number of bikes to 0.99 of the initial number, and all things held constant. In other words for a unit increase in humidity levels, the expected decline in the number of bikes on road is 0.67%. A unit increase in the wind speed is equivalent to 0.015 decrease in the magnitude of normalized wind speed. Correspondingly, the effective number of bikes is 0.985times the initial number, ceteris paribus. Thus, the expected percentage decline in the number of commercial bikes due to a unit increase in the wind speed is 1.5%.
