This paper aims to provide different methods to compute the customized hazard ratio for covariates with multiplecategories. The emphasis is on illustrative examples of comparisons for manually generating the dummy variables in SAS V8.2 and using CLASS, CONTRAST, and HAZARDRATIO statements in SAS V9.2...

The fact that a lot of numbers are involved in the counting and the proportions are high allows the sampling distributions of counted objects to approximate Normality. Unless either of these conditions is met, the distribution will not be Normal. This chapter presents a BASIC program to compute ...
A moving average is better at adapting to changes by considering a few nearby data points to compute the mean. Yet, it can still lead to biased results if the data is not missing at random. Interpolation You can use interpolation to impute missing data. Interpolation methods aim to estimate ...
To compute the mixture effect on species dominant height, we followed Vallet and Perot (2016): for each stand and each species, we compared observed dominant height to the expected dominant height in case the species had grown in a monospecific stand under the same environmental conditions (here...
Compute the precipitation depth for the 10- and 30-minute durations for each of the return periods. To do this, use the formulas seven and eight as provided in the HYDRO-35 publication. These formulas are generally valid for all parts of the country, so they can be used for other maps ...
How to Run a KS Test in SPSS Step 1:Analyze → descriptive statistics → explore Step 2:Move the variables you want to test for normality over to the Dependent List box. Step 3:(Optional if you want to check for outliers) Click Statistics, then place a check mark in the Outliers box...

Compute easily statistical tests (t_test() or wilcox_test()) using the rstatix package Auto-compute p-value label positions using the function add_xy_position() [in rstatix package]. Add the p-values to the plot using the function stat_pvalue_manual() [in ggpubr package]....
4 both problems are reformulated as linear quadratic tracking control problems where the system equations have a time-varying intercept following a mean reverting, or ‘Return to Normality’, model and the associated TVP-controls are derived. Then the optimizing model for monetary policy used in ...
