This can mean predicting the probability of an event taking place in the future to estimate the exact time it will happen. Predictive analytics provides insight into the forecast trends based on momentary events. Usually, it goes hand in hand with descriptive analytics. Diagnosticĭiagnostic analytics offers a deeper insight into a specific issue, uncovering its source and isolating the root-cause. This means deriving patterns from past events or interpreting them so that you can shape better strategies in the future.

Essentially, the statistical software should transform raw data into an easily understandable form. This is the most common form of data analysis-it provides an overview of key metrics and measures, describing in detail something that has taken place in the past. The best software should support the use cases mentioned below. There are a variety of approaches for data analysis including business intelligence, real-time analytics, predictive analytics, and machine learning. What follows is a list of some of the crucial functionalities we look for in a product. Next, we take note of the features of statistical software programs. The Sign test is intended for checking if two related variables are different, but only considers direction.

The Wilcoxon sign-rank test looks for differences between two related variables, considering the magnitude and direction of difference. The Wilcoxon rank-sum test is one type of non-parametric test that assesses the difference between two independent variables, considering the magnitude and direction of difference. Non-parametric tests are used when the data doesn’t meet the hypothesis required for parametric tests. A multiple regression test meanwhile determines how a change in the predictor variable anticipates the change in the outcome variable. Simple regression is a test that assesses how the change in the predictor variable predicts the change in the outcome variable. The regression tests provided by statistical analysis systems determine whether the change in one variable predicts change in another. The ANOVA test is intended for finding differences between group means after other variance in the outcome the variable is accounted for. Paired T-test looks for differences between two variables from the same population while an independent T-test targets differences between the same variables from different populations. Statistical software tools use comparison of means to test the difference between the means of variables. Spearman correlation checks the strength of association between two ordinal variables while Chi-square looks at the strengths of the associations between two categorical variables. Pearson correlations test the strength of the cooperation between two continuous variables. There are several types of correlational tests. CorrelationalĬorrelational tests look for relations between variables. The best software should be able to conduct the essential statistical tests outlined below.

Cloud-based software doesn’t require license purchasing while the ones that are deployed on-premise can offer perpetual or subscription-based licenses. Next, we consider the type of deployment. This aspect might influence the pricing, feature set, setup, and installation process, which is why it’s important to use to get the bigger picture before starting our evaluation.Īdditionally, there might be some statistical software packages that serve specific industries so we take note of this too. Some of them focus on small businesses and startups while others are a better fit for larger organizations. Classificationīefore starting our comparison, we classify the software depending on the business size they cater to. Read along to find what else we take into consideration when curating our list of leading statistical programs. We make sure that each product listed here meets these requirements. This type of software needs to offer robust collection, transformation, and organization of data to detect useful information and provide accurate output that will enable you to make fact-based decisions.
