Factor Analysis Sample Clauses

Factor Analysis. To explore the different dimensions captured in each fatigue questionnaire and also assess their relationship with anxiety and depression, simple descriptive analyses were applied to the data, as well as ▇▇▇▇▇▇▇▇’▇ correlations. In this study, correlations of r≥0.6 are reported as strong correlations, r≥4 and <6 as moderate correlations and r<4 as weak correlations. Cronbach’s alpha was used to test the internal validity of the items in the fatigue questionnaires. Cronbach’s alpha is a coefficient of internal consistency which is commonly used as an estimate of the reliability of a psychometric test. Where validity is concerned with the extent to which an instrument measures what it is intended to measure. [Following this an exploratory factor analysis of the fatigue questionnaires was undertaken. A rotated factor matrix was performed with all the questions from each questionnaire as well as the fatigue VAS and the HADS scores. In order to identify the most appropriate questions and reduce down the number of items, all items which were not highly correlated were excluded (loading <0.6). To further reduce this both clinical interpretation and statistics were employed to exclude any very similar questions. The questions were the examined by the investigator and a second rheumatologist and using clinical judgement and after agreement between the two clinicians if two questions had almost identical wording or it was felt they were asking the same question then the question with the lowest loading was rejected and the question with the highest loading was retained. For example: I feel nervous and I feel tense were felt to be asking the same question. The loading into the factor analysis rotated factor analysis was 0.889 for I feel nervous and 0.672 for I feel tense; therefore, I feel tense was excluded from the final model. Consideration was also made to ensure that each dimension was represented.

Factor Analysis. Factor Analysis (FA) is not like the other techniques mentioned here, in the sense that it can not be used as a dimensionality reduction before a classifier. Its analysis stands on its own. FA is used to identify the structure underlying the variables and to estimate scores to measure latent factors themselves. In Factor Analysis, only the shared variance is analysed in contrast to PCA where all the observed variance is analysed. Furthermore, FA explicitly assumes the existence of latent factors underlying the observed data. PCA instead seeks to identify variables that are composites of the observed variables (▇▇▇▇, s.

  • Risk Analysis The Custodian will provide the Fund with a Risk Analysis with respect to Securities Depositories operating in the countries listed in Appendix B. If the Custodian is unable to provide a Risk Analysis with respect to a particular Securities Depository, it will notify the Fund. If a new Securities Depository commences operation in one of the Appendix B countries, the Custodian will provide the Fund with a Risk Analysis in a reasonably practicable time after such Securities Depository becomes operational. If a new country is added to Appendix B, the Custodian will provide the Fund with a Risk Analysis with respect to each Securities Depository in that country within a reasonably practicable time after the addition of the country to Appendix B.

  • Quantitative Analysis Quantitative analysts develop and apply financial models designed to enable equity portfolio managers and fundamental analysts to screen potential and current investments, assess relative risk and enhance performance relative to benchmarks and peers. To the extent that such services are to be provided with respect to any Account which is a registered investment company, Categories 3, 4 and 5 above shall be treated as “investment advisory services” for purposes of Section 5(b) of the Agreement.”

  • Escrow Analysis If applicable, with respect to each Mortgage Loan, the Seller has within the last twelve months (unless such Mortgage was originated within such twelve month period) analyzed the required Escrow Payments for each Mortgage and adjusted the amount of such payments so that, assuming all required payments are timely made, any deficiency will be eliminated on or before the first anniversary of such analysis, or any overage will be refunded to the Mortgagor, in accordance with RESPA and any other applicable law;

  • Sampling and Analysis The sampling and analysis of the coal delivered hereunder shall be performed by Buyer upon delivery of the coal to Buyer’s facility, and the results thereof shall be accepted and used as defining the quality and characteristics of the coal delivered under this Agreement and as the Payment Analysis. All analyses shall be made in Buyer’s laboratory at Buyer’s expense in accordance with ASTM standards where applicable, or industry-accepted standards in other cases. Samples for analyses shall be taken in accordance with ASTM standards or other methods mutually acceptable to both parties. Seller shall transmit its “as loaded” quality analysis to Buyer as soon as possible. Seller’s “as-loaded” quality shall be the Payment Analysis only when Buyer’s sampler and/or scales are inoperable, or if Buyer fails to obtain a sample upon unloading. Seller represents that it is familiar with Buyer’s sampling and analysis practices, and that it finds them to be acceptable. Buyer shall notify Seller in writing of any significant changes in Buyer’s sampling and analysis practices. Any such changes in Buyer’s sampling and analysis practices shall, except for ASTM or industry-accepted changes in practices, provide for no less accuracy than the sampling and analysis practices existing at the tune of the execution of this Agreement, unless the Parties otherwise mutually agree. Each sample taken by Buyer shall be divided into four (4) parts and put into airtight containers, properly labeled and sealed. One (1) part shall be used for analysis by Buyer. One (1) part shall be used by Buyer as a check sample, if Buyer in its sole judgment determines it is necessary. One (1) part shall be retained by Buyer until thirty (30) days after the sample is taken (“Disposal Date”), and shall be delivered to Seller for analysis if Seller so requests before the Disposal Date. One (1) part (the “Referee Sample”) shall be retained by Buyer until the Disposal Date. Seller shall be given copies of all analyses made by Buyer by the fifth (5th) business day of the month following the month of unloading. In addition, Buyer shall send Seller weekly analyses of coal unloaded at Buyer’s facilities. Seller, on reasonable notice to Buyer, shall have the right to have a representative present to observe the sampling and analyses performed by Buyer. Unless Seller requests an analysis of the Referee Sample before the Disposal Date, Buyer’s analysis shall be used to determine the quality of the coal delivered hereunder and shall be the Payment Analysis. The Monthly Weighted Averages of specifications referenced in §6.1 shall be based on the individual Shipment analyses. If any dispute arises with regard to the analysis of any sample before the Disposal Date for such sample, the Referee Sample retained by Buyer shall be submitted for analysis to an independent commercial testing laboratory (“Independent Lab”) mutually chosen by Buyer and Seller. For each coal quality specification in question, if the analysis of the Independent Lab differs by more than the applicable ASTM reproducibility standards, the Independent Lab results will govern, and the prior analysis shall be disregarded. All testing of the Referee Sample by the Independent Lab shall be at requestor’s expense unless the Independent Lab results differ from the original Payment Analysis for any specification by more than the applicable ASTM reproducibility standards as to that specification. In such case, the cost of the analysis made by the Independent Lab shall be borne by the party who provided the original Payment Analysis.

  • Independent Analysis Each Party hereby confirms that its decision to execute this Agreement has been based upon its independent assessment of documents and information available to it, as it has deemed appropriate.
