Find or make your target class attribute. b) the description of used classification methods and their validation process (changing their parameters e.g. minsplit, cp, k-fold crossvalidation, boosting, bagging, adding cost matrices to them, modifing input data e.g. standardization i.e. standard score, normalization, removing NA and so on). c) the validation process summary including ROC plots and their comparison. d) You may use some clustering methods for not labeled datasets (without an obvious target attribute). After this operation you can learn classifiers utilising input data and obtained cluster labels. e) Enclose please your R code with comments and links to data used in R code (if it was changed before [login to view URL] then dropbox links to your new data).

    The task is to do a quantitative analysis of equity crowdfunding. I am trying to figure out the success drivers of successful statups. I have collected basic data. The end goal is to predict the valuation a hypothetical startup based on the other successful cases. The basic idea will be to feed in as many key variables and do a regression of the valuations on revenue, and then to separate out and do similar regression on the successful and the unsuccessful cases, to see if there is a difference.

    Hi there, I am doing an economic research in which it uses STATA for the data analysis. Some of my results now do not seem to be correct, perhaps due to some missing specifications that I am not aware of. The estimation method I am using is the two step GMM of dynamic panel data model, which I am still not fully familiar with the model itself.

    Instruction: Always state your null and alternative hypotheses before reporting tests of significance. Include your R codes or SAS codes in an appendix of your report Be selective in the outputs you report. Include only the most relevant outputs and the ones you want to interpret [e.g., ANOVA tables, Confidence intervals, P-values, etc.]. Sometimes, SAS gives you a very long output. Also avoid copy-pasting ERROR messages from R console. Always, interpret your results! *** Question I: Exercise #7 (Data in Table 6.33) a) Calculate the descriptive statistics by treatment (mean, standard deviation, number of observations, boxplot). b) Is the design balanced or unbalanced? c) Construct the analysis of variance (ANOVA) table and test whether the drugs are equally effective. d) Apply the Tukey multiple comparison procedure to find out significantly different drugs. e) Test at α = 5% whether the average of the standard drug and the new experimental drug is significantly different from the placebo. Construct a 95% confidence interval for the contrast. f) Test whether the normality and variance homogeneity assumptions are satisfied. Question II: Exercise #3 (Data in Table 6.30), + Estimate the ratio of the variance components by a confidence interval. Variance component estimations is also frequently used in animal breeding. Search for "breeding value" and describe it.
