The following code will create a data set with just the bmi variable. ![]() Note that you cannot use a drop statement and a keep statement in the same data step. Which one to use depends simply on whether or not you want to drop or keep more variables. The keep statement (basically) does the same thing as the drop statement but in reverse, by only keeping the variables we have specified. Set mat013.MMM(drop=weight_in_kg height_in_metres) Note that the following code would not give the required output as we are trying to drop the variables from the original data set, however we need those variables to calculate the bmi: data mat013.MMM_with_BMI_nhw We use a "drop" statement to get rid of those variables: data mat013.MMM_with_BMI_nhw(drop=weight_in_kg height_in_metres) Let us consider the previous example and assume that we want our MMM_with_BMI data set without the weight and height variables. We do this with the "drop" or "keep" statement. Recalling how SAS handles a data step (using the pdv as described previously), one immediate way of improving efficiency is to ensure that the pdv only "transports" the variables we require. ![]() In this section we'll take a quick look at two simple ways of improving the efficiency of a data step. It's worth checking the web for a full list of various SAS functions (there are a huge amount of them). We can also do operations on strings, the following code replaces the variable "Sex" with the first entry of "Sex" (which gets rid of the Male - M and Female - F issue). Some of the arithmetic functions are shown. The following code creates a new data set call MMM_with_BMI, with a new variable "BMI" as a function of the height and weight variables in the MMM dataset in the mat013 library. SAS creates the descriptive portion of the SAS data set (viewable using the "contents" procedure).Īn example of how this works with concatenation and an example of how this works with merging is shown.Ĭreating new variables using various arithmetic and/or string relationships is relatively straightforward in SAS. (If a "by" statement is used (for example when merging two data sets) the PDF does not empty if there are still observations with the same value of the "by" variable). SAS reads in the data line by line using the PDF. SAS creates a PDV to store the information for all the variables required from the data step.SAS checks the data step for any unrecognized keywords and syntax errors.The basic steps of compiling a data step are as follows: In this section we'll explain how it uses the "program data vector" (pdv) to efficiently handle data. SAS is able to handle very large data sets because of the way data steps work. The result is shown in (note that the above code makes use of the substr function that we will see later). The following code selects only the elements of the above data set that start with a D. Merge mat013.first_data_set mat013.other_data_set ĭata steps can be used in conjunction with the where statement to select certain variables. The following code would merge the two data sets first_data_set and other_data_set in the mat013 library as shown. Note that the two data sets must be sorted on the merge variable prior to merging. To merge two data sets (as shown pictorially) we use the following syntax: data The following code concatenates the jjj and mmm data sets as shown. To concatenate two data sets (as shown pictorially) we use the following syntax: data The following code simply creates a data set in the work library called "j" that is a copy of the data set jjj located in the mat013 library. Copying a data set (with new variables). ![]() A data step is a type of SAS statement that allows you to manipulate SAS data sets.

The wide number of partnerships and guiding food labeling have changed Danish food products and solutions into a healthier direction with a great impact on Danish consumer behaviour. Together with the industry, health NGOs and academia we speak with a single voice and move forward in the same direction, working towards the same agenda of creating healthier food products for Danes and for our export markets.įood producers invest heavily in research and development and as a result, several new healthy food solutions are made available to the consumer The close collaboration across the food value chain has been significant in developing the many partnerships that dominate the food sector today, as well as sharpened government strategies. Healthier products create healthier people Examples include the Danish Wholegrain Partnership that creates the foundation for a whole new line of developed products with an increased amount of whole grain such as pasta, cereals or bread. Public-private partnerships between industry, academia, government, and health NGOs draw on these guidelines to set the direction for new product development and consumer outreach. This has resulted in new climate-friendly dietary guidelines, research and development, partnerships and innovative nutritional solutions that will continue to provide more targeted nutrition for the society at large. ![]() Successive Danish governments have actively demonstrated their commitment to improving consumer access to healthier foods. To this end, government-backed initiatives such as the Keyhole label encourage consumers to make healthy choices when buying food.Īs a business partner to the Danish food cluster, you can draw advantage from Den-mark’s experience within developing healthy food products and solutions Governmental guidance support healthy food choices In Denmark we have managed to bring competences together in a way that not only incentivises companies to continually innovate better and healthier products, but also give consumer guidelines that make selecting healthy food products easier for the consumer.

Pirelli has long been at the mercy of the sport in order to increase the entertainment aspect, with thermal degradation identified as a way of creating strategic differences between the teams and drivers. 1, 73760 Ostfildern-Scharnhausen, Germany ( aerodynamicists will also find themselves challenged by the changes, as the lower profile tyre will behave differently to the outgoing rubber - with the dynamic behaviour of the tyre creating inconsistencies that they'll be keen to get a handle on.Ī number of aerodynamic tricks have been used in the sport’s recent past to try and mitigate the effect known as ‘tyre squirt’. But, with many of those design features either removed or heavily constrained, teams will have to find new ways to deal with the resultant change in the tyre’s stiffness and sidewall height. Additional equipment and accessories (attachment parts, tire size, etc.) can change relevant vehicle parameters, such as weight, rolling resistance and aerodynamics and, like weather and traffic conditions as well as individual driving style, influence a vehicle’s electric power consumption, CO₂ emissions and performance figures.įurther information on official fuel consumption figures and the official specific CO₂ emissions of new passenger cars can be found in the “Guide on the fuel economy, CO₂ emissions and power consumption of all new passenger car models,” which is available free of charge at all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. They are provided only for the purpose of comparison between the various vehicle types. If NEDC values are indicated as a range, they do not refer to one, specific vehicle and are not an integral element of the offer.
