Executing UDF

 -- Create @RideHrs

DECLARE @RideHrs AS numeric

-- Execute SumRideHrsSingleDay function and store the result in @RideHrs

EXEC @RideHrs = dbo.SumRideHrsSingleDay @DateParm = '3/5/2018' 

SELECT 

  'Total Ride Hours for 3/5/2018:', 

  @RideHrs



Executing a Table Function


-- Create @StationStats

DECLARE @StationStats TABLE(

StartStation nvarchar(100), 

RideCount int, 

TotalDuration numeric)

-- Populate @StationStats with the results of the function

INSERT INTO @StationStats

SELECT TOP 10 *

-- Execute SumStationStats with 3/15/2018

FROM dbo.SumStationStats('3/15/2018') 

ORDER BY RideCount DESC

-- Select all the records from @StationStats

SELECT * 

FROM @StationStats



Use SP to DELETE

Create a stored procedure named cuspRideSummaryDelete in the dbo schema that will delete an existing record in the RideSummary table and RETURN the number of rows affected via output parameter.


CREATE PROCEDURE dbo.cuspRideSummaryDelete

-- Specify @DateParm input parameter

(@DateParm date,

     -- Specify @RowCountOut output parameter

     @RowCountOut INT OUTPUT)

AS

BEGIN

-- Delete record(s) where Date equals @DateParm

DELETE FROM dbo.RideSummary

WHERE DATE = @DateParm

-- Set @RowCountOut to @@ROWCOUNT

SET @RowCountOut = @@ROWCOUNT

END;

Binomial Test in Python

  Binomial Test Let’s imagine that we are analyzing the percentage of customers who make a purchase after visiting a website. 1000 customers visited the site this month, and 58 of them made a purchase. The marketing department reports that historical data suggests about 72 of every 1000 visitors make a purchase. Thus, they estimate that the probability of any particular customer making a purchase is 7.2%. We would like to know if this month’s number, 58 purchases, is significantly different from normal or a reasonable fluctuation due to random chance. In previous exercises, we collected samples of numerical information (eg. order price) and then used the mean and standard deviation of those samples to make comparisons. In contrast, we now have a sample where each unit (a visitor) falls into one of two discrete categories: “made a purchase” “did not make a purchase” Instead of comparing sample means, we want to compare the percent in the “made a purchase” category to some expectatio...

Slicing and Indexing in Python Pandas

Python Syntax and Functions Part2 (Summary Statistics)

The  .agg()  method allows you to apply your own custom functions to a DataFrame, as well as apply functions to more than one column of a DataFrame at once, making your aggregations super efficient. In the custom function for this exercise, "IQR" is short for inter-quartile range, which is the 75th percentile minus the 25th percentile. It's an alternative to standard deviation that is helpful if your data contains   import numpy as np def iqr(column):     return column.quantile(0.75) - column.quantile(0.25) # Update to print IQR and median of temperature_c, fuel_price_usd_per_l, & unemployment print(sales[["temperature_c", "fuel_price_usd_per_l", "unemployment"]].agg([iqr, np.median])) Calulating Cumulative Statistics Syntax = df.drop_duplicates sales_1_1 = sales_1_1.sort_values("date") # Get the cumulative sum of weekly_sales, add as cum_weekly_sales col sales_1_1["cum_weekly_sales"] = sales_1_1["weekly_sales...
