![]() Rain = rain %>% drop_na(WindGustDir, WindDir9am, WindDir3pm, RainToday, RainTomorrow) Doing so reduces our dataset to 24,351 observations. The following code checks for any missing, or “NA”, values in our categorical variables and eliminates the entire observation. For simplicity, we’ll opt to eliminate any observations with missing categorical values. The dataset contains both categorical and quantitative variables, both of which have missing values. ![]() If we were to remove all observations with a missing value, our dataset size would reduce by half to 13,887 observations. Cloud9am and Cloud3pm suffer the most from missing data, with almost 40% of values missing. the total missing can range widely from 64 “MaxTemp” values to over 11,341 missing values on cloud cover. With over 28,000 observations, it’s not too surprising to see most variables are each missing at least a few values. Phase one of this project will be preparing the data for analysis by eliminating or filling those missing values, then identifying potentially strong predictors of the “RainTomorrow” variable. Most variables are missing a number of values, so we’ll need to sanitize the data before proceeding. Variables include information such as wind speed, humidity, temperature, and cloud cover. This dataset includes 28,003 observations with 20 variables describing various factors. Sunrise will be at 06:35 am, and sunset at 07:25 pm, making it a total of 12 hours and 77 minutes of visible light.The data provided includes dates from November 2007 to late-June 2017. Atmospheric pressure will be normal with average pressure of 1007 mb. The visibility is expected to be ideal with average visibility of 7.208 mi throughout the day. The dew point will range from 44° up to a maximum value of 46° around 12 am. There's seems to be also high probability of some rain during throughout the day, and also during the night. The wind will be light, and will get up to 22 m/h, blowing from the The day will have appropriate humidity, with average humidity of 95%, ranging from 47.5% to a maximum value of 95% at about 2 am. The highest temperature of the the day is going to be 47° at about 4 pm. There is also a chance for few clouds in the early morning, and there's seems to be also high probability of many clouds at night. The weather tomorrow, will be moderate rain throughout the day, with some clouds before dawn. There's no risk of weed pollen, and as for grass pollen, this day is prospective to have very low risk. Tree pollen on this day is expected to have very low risk. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. On average, the air quality on this day will be moderate, meaning that air quality is acceptable. Sunrise will be at 06:37 am, and sunset at 07:24 pm, making it a total of 12 hours and 78 minutes of daylight. ![]() The visibility is prospective to be good with average visibility of 7.208 mi throughout the day.
